How to Fix Common WordPress Errors Without Losing Your Website Content

Discover practical, beginner-friendly solutions to common WordPress problems, protect your website content and restore your website safely without unnecessary panic or expensive mistakes.

Imagine spending months creating valuable articles, publishing business information, designing your website and attracting visitors, only to open your website one morning and discover that it is displaying an error message.

Your homepage may suddenly become blank. Your WordPress dashboard may refuse to open. A plugin update may cause your website to stop functioning. Perhaps you see a message saying that your website has experienced a critical error.

For many website owners, this experience creates immediate fear. The first thought is often that everything has been lost.

However, here is an important truth every WordPress website owner should understand:

A website error does not automatically mean that your website content has been deleted.

Your articles, pages, images and database records may still be safely stored on your hosting account even when the website itself is temporarily inaccessible.

The real challenge is identifying what caused the problem and correcting it without making the situation worse.

This comprehensive guide from Richems Digital explains how to identify, understand and resolve common WordPress errors using practical methods that help protect your website content.

1. Understanding Common WordPress Errors

WordPress is a powerful content management system, but it depends on several components working together correctly.

  • WordPress core files.
  • Your website database.
  • Installed plugins.
  • Your active WordPress theme.
  • PHP and server configurations.
  • Hosting resources and permissions.
  • Website security and access settings.

When one or more of these components develops a problem, your website may stop functioning correctly.

For example, an outdated plugin may conflict with a newer WordPress version. A theme update may introduce a coding problem. A hosting server may temporarily run out of available resources.

Professional advice: Always investigate the cause of an error before attempting a repair. Successful website maintenance is not about making random changes until something works; it is about making informed corrections while protecting existing information.

2. What to Do Before Fixing Any WordPress Error

Before attempting to repair your website, establish a safety point. Your website content represents time, effort and sometimes years of business development. Protecting it should always come before troubleshooting.

Step 1: Create a Complete Website Backup

A proper WordPress backup should contain two important components:

  • Website files: Themes, plugins, uploaded images, documents and other website resources.
  • Database: Published posts, pages, comments, website settings, user information and other stored content.

A backup containing only website files may not preserve your articles and pages. Similarly, a database-only backup may not contain your uploaded images and other media files.

Make sure you have both.

If you use Hostinger, log in to your hosting account and check the available backup options under your website management dashboard.

You can also use reputable WordPress backup plugins:

Download or store your backup somewhere separate from your hosting account whenever possible.

Step 2: Record the Error Message

Take a screenshot or write down the exact error message displayed on your website.

Examples include:

  • There has been a critical error on this website.
  • Error establishing a database connection.
  • 500 Internal Server Error.
  • 403 Forbidden.
  • 404 Page Not Found.
  • Allowed memory size exhausted.

These messages provide valuable clues about what may be wrong.

Step 3: Identify What Changed Before the Error Appeared

Ask yourself:

  • Did I recently install a new plugin?
  • Did I update my WordPress theme?
  • Did I change any website code?
  • Did I modify my website configuration?
  • Did I recently migrate my website?
  • Did my hosting provider make any changes?

Step 4: Test Your Website Properly

Open your website in an incognito browser window or use another device. Sometimes, an error is caused by cached files rather than the actual website.

Important: Never delete your WordPress installation, database, wp-content folder or website files simply because your website is displaying an error. These components may contain your valuable content and configuration.

3. How to Fix the WordPress White Screen of Death

The White Screen of Death is one of the most frustrating WordPress problems. Instead of displaying your homepage or dashboard, the website shows a completely blank screen.

Common Causes

  • Incompatible plugins.
  • Theme-related coding errors.
  • Insufficient PHP memory.
  • Corrupted WordPress files.
  • PHP compatibility problems.

How to Fix It

Method 1: Disable Recently Installed Plugins

If you can access your WordPress dashboard, navigate to Plugins → Installed Plugins.

Deactivate the plugin you installed or updated immediately before the problem started. Refresh your website to see whether the problem disappears.

Method 2: Disable Plugins Through File Manager

If your dashboard is inaccessible, log in to your hosting control panel.

  1. Open File Manager.
  2. Locate your WordPress installation directory, commonly public_html.
  3. Open wp-content.
  4. Find the plugins folder.
  5. Rename plugins to plugins-disabled temporarily.
  6. Refresh your website.

If the website becomes accessible, a plugin conflict may be responsible.

Rename the folder back to plugins. Then deactivate or isolate the problematic plugin individually.

Method 3: Switch to a Default WordPress Theme

If the problem continues after disabling plugins, your active theme may be responsible.

Using the hosting File Manager, inspect wp-content/themes. Make sure a compatible default WordPress theme is available before attempting to switch themes.

You can also ask your hosting provider or developer to help switch the active theme safely.

Expected result: If the problem was caused by a plugin or theme conflict, your website may become accessible again without deleting your existing articles, pages or database content.

4. How to Fix the WordPress Critical Error Message

WordPress sometimes displays this message:

There has been a critical error on this website. Please check your site admin email inbox for instructions.

This usually indicates that a PHP error has prevented WordPress from completing an operation.

Step 1: Check Your Administrator Email

WordPress may send an automatic recovery email containing information about the error.

Check your website administrator email address, including the spam folder.

Step 2: Enable WordPress Debug Logging

If you are comfortable editing website files, locate wp-config.php in your WordPress root directory.

Configure the following debugging settings, taking care not to create duplicate definitions if they already exist:

define('WP_DEBUG', true); define('WP_DEBUG_LOG', true); define('WP_DEBUG_DISPLAY', false);

This enables error logging while preventing error details from being displayed publicly to website visitors.

After reproducing the problem, inspect:

wp-content/debug.log

The log may identify the plugin, theme or PHP file responsible for the error.

Security reminder: Debug logging is intended for troubleshooting. Once the problem has been resolved, disable debugging and protect or remove diagnostic logs that may contain sensitive information.

Step 3: Correct the Identified Problem

If the log identifies a particular plugin, update, deactivate or replace that plugin as appropriate.

If it identifies your theme, contact the theme developer or temporarily use a compatible default theme.

Avoid editing WordPress core files to correct a plugin or theme problem.

5. How to Fix the 500 Internal Server Error

The 500 Internal Server Error means your web server encountered an unexpected problem while processing a request.

It does not necessarily mean your website content is damaged.

Common Causes

  • Corrupted .htaccess file.
  • Plugin conflicts.
  • Theme compatibility problems.
  • PHP configuration errors.
  • Insufficient hosting resources.
  • Incorrect file permissions.

Solution 1: Rename the .htaccess File

  1. Open your hosting File Manager.
  2. Navigate to your WordPress root directory.
  3. Locate .htaccess. Enable hidden-file visibility if necessary.
  4. Rename it to .htaccess-backup.
  5. Refresh your website.

If your website becomes accessible, the original .htaccess file may have contained incorrect or conflicting rules.

Solution 2: Generate a New Permalink Configuration

If you can access your dashboard:

  1. Go to Settings.
  2. Select Permalinks.
  3. Keep your preferred permalink structure.
  4. Click Save Changes.

WordPress may regenerate the necessary rewrite rules.

Solution 3: Check Your PHP Configuration

Check whether your hosting account is running a PHP version supported by your current WordPress installation, theme and plugins.

Use your hosting dashboard to select a compatible, currently supported PHP version.

Do not randomly downgrade PHP simply to hide an error. An outdated PHP version may create security and compatibility problems.

If the error continues, consult your hosting provider’s server error logs.

Additional guidance: Hostinger’s WordPress 500 Error Guide.

6. How to Fix Error Establishing a Database Connection

This error appears when WordPress cannot communicate with its database.

Your database contains essential website information, including posts, pages, comments and settings.

Therefore, approach this problem carefully.

Common Causes

  • Incorrect database credentials.
  • Database server downtime.
  • Corrupted database tables.
  • Incorrect database configuration.
  • Hosting resource limitations.

Solution 1: Check Your Database Credentials

Locate wp-config.php in your WordPress root directory.

Look for these settings:

define('DB_NAME', 'database_name'); define('DB_USER', 'database_username'); define('DB_PASSWORD', 'database_password'); define('DB_HOST', 'localhost');

Compare these details with the actual database information provided by your hosting company.

The database host is not always localhost. Use the exact value supplied by your hosting provider.

Never publish your wp-config.php file or share your database password with an unknown person. These details provide access to important parts of your website.

Solution 2: Check Your Hosting Database Status

Log in to your hosting dashboard and inspect your database management section.

Confirm that:

  • Your database exists.
  • The database user is correctly assigned.
  • The database server is operational.
  • Your hosting account has not exceeded its resource limits.

Solution 3: Repair the Database Carefully

WordPress provides a database repair facility, but it should only be used when necessary and after creating a backup.

If you are experienced with WordPress configuration, you may temporarily add the following line to wp-config.php:

define('WP_ALLOW_REPAIR', true);

Then visit:

https://yourdomain.com/wp-admin/maint/repair.php

Replace yourdomain.com with your actual website domain.

Follow the available repair instructions.

Immediately remove the WP_ALLOW_REPAIR line after completing the repair.

This repair endpoint does not require normal authentication while enabled, so never leave it active.

7. How to Fix WordPress Plugin Conflicts

Plugins extend WordPress functionality. They help website owners create contact forms, improve SEO, secure websites, optimize images and introduce additional features.

However, installing too many plugins or using incompatible plugins can create serious problems.

Signs of a Plugin Conflict

  • Your website becomes unusually slow.
  • The dashboard stops responding.
  • Some website features disappear.
  • Your website displays unexpected error messages.
  • Your editor stops saving changes.

How to Identify the Problematic Plugin

  1. Back up your website.
  2. Deactivate all plugins temporarily if necessary.
  3. Check whether the website works.
  4. Reactivate plugins individually.
  5. Test your website after each activation.
  6. Identify the plugin that causes the problem.
  7. Update, replace or remove the incompatible plugin.

Before removing a plugin, determine whether it stores important information or performs essential functions.

Smart website management: A professional website does not need dozens of plugins. Install only the tools that serve a clear purpose, maintain them regularly and remove unnecessary software responsibly.

8. How to Fix WordPress Theme Problems

Your WordPress theme controls much of your website’s appearance and layout.

A theme problem may cause missing sections, distorted layouts, broken menus or a completely inaccessible website.

Possible Causes

  • Incomplete theme updates.
  • Theme incompatibility with WordPress.
  • Conflicts with installed plugins.
  • Incorrect custom CSS or PHP modifications.
  • Damaged theme files.

Recommended Solutions

  1. Check whether a theme update is available.
  2. Temporarily activate a compatible default theme.
  3. Test whether the error disappears.
  4. Inspect custom CSS and additional code snippets.
  5. Contact the theme developer if the problem persists.

If you use a child theme, preserve its files and customizations before making changes.

9. How to Fix WordPress Login Problems

Being unable to access your WordPress dashboard can prevent you from managing your website.

Common login problems include:

  • Incorrect username or password.
  • Too many failed login attempts.
  • Login page redirect loops.
  • Security plugin restrictions.
  • Incorrect website URL settings.
  • Browser cookie problems.

Solution 1: Reset Your Password

Visit:

https://yourdomain.com/wp-login.php

Select the Lost your password option and follow the instructions.

Solution 2: Clear Browser Cookies and Cache

Sometimes, old browser information interferes with the login process.

Clear your browser cache and cookies, then attempt to log in again.

Solution 3: Check Security Plugins

A security plugin may temporarily block your login after several unsuccessful attempts.

If necessary, inspect the plugin settings through your hosting account and follow its account recovery procedure.

Solution 4: Check Your Website Address

Incorrect WordPress Address and Site Address settings can create login redirect problems.

If the issue began after changing your domain, SSL certificate or website URL, contact your hosting provider or a WordPress professional to check the configuration.

A 404 error means the requested page cannot be found at the address being visited.

This can happen even when the page still exists in your WordPress dashboard.

Common Causes

  • Incorrect permalink settings.
  • Changes to page URLs.
  • Missing rewrite rules.
  • Incorrect server configuration.
  • Deleted or unpublished pages.

How to Fix the Problem

  1. Log in to your WordPress dashboard.
  2. Navigate to Settings → Permalinks.
  3. Review your current permalink structure.
  4. Click Save Changes without unnecessarily changing your preferred structure.
  5. Test the affected pages.

If the problem continues, inspect your server rewrite configuration or ask your hosting provider for assistance.

Important SEO Consideration

Changing a published page URL without creating a proper 301 redirect can result in broken links and lost search traffic.

If you must change a URL, redirect the old address to the most relevant new page.

11. How to Fix WordPress Memory Limit Errors

WordPress requires sufficient server memory to run its themes, plugins and other processes.

When a website exceeds its allocated PHP memory limit, it may display an error such as:

Fatal error: Allowed memory size exhausted.

Possible Causes

  • Resource-intensive plugins.
  • Large website operations.
  • Heavy themes or scripts.
  • Insufficient hosting resources.

Possible Solution

Some hosting environments allow WordPress memory settings to be adjusted through wp-config.php.

For example:

define('WP_MEMORY_LIMIT', '256M');

Add the setting before the following line, if present:

/* That's all, stop editing! Happy publishing. */

However, increasing the WordPress memory request does not guarantee that your hosting plan will provide that amount. Your hosting provider may enforce a lower PHP memory limit.

If the error continues, investigate the plugin or process consuming excessive memory and contact your hosting provider about the available PHP memory allocation.

Professional recommendation: Do not keep increasing memory limits without investigating the cause. A poorly optimized plugin can continue consuming excessive resources even after the memory allocation is increased.

12. How to Fix Image and Media Upload Errors

Images are important to a professional website. They improve visual presentation, support communication and make articles more engaging.

However, WordPress sometimes experiences problems when uploading images, videos or documents.

Common Causes

  • Files exceeding the permitted upload size.
  • Unsupported file formats.
  • Incorrect file permissions.
  • Insufficient hosting resources.
  • Temporary server problems.
  • Plugin conflicts.

Solution 1: Check the File Size

If your image is too large, compress it before uploading.

Use properly optimized JPEG, PNG or WebP images where appropriate.

Solution 2: Check Supported File Formats

Make sure your uploaded file uses a format supported by your WordPress installation.

Avoid uploading unknown file types or files from untrusted sources.

Solution 3: Check Upload Permissions

WordPress needs appropriate permissions to save uploaded files in its media directory.

The usual directory is:

wp-content/uploads/

If uploads fail repeatedly, ask your hosting provider to inspect the directory permissions and ownership.

Solution 4: Check Your Hosting Upload Limits

Your hosting provider may enforce PHP upload limits.

Check the following PHP settings with your hosting provider:

  • upload_max_filesize
  • post_max_size
  • max_execution_time

These settings should be configured according to your website requirements and hosting plan.

13. How to Protect Your Website from Future Problems

Fixing a WordPress error is important, but preventing future problems is even more valuable.

A properly maintained website is more reliable, secure and easier to manage.

1. Keep WordPress Updated

Install security and maintenance updates for WordPress core, themes and plugins.

Before major updates, create a complete backup and check compatibility.

2. Use Trusted Plugins and Themes

Download themes and plugins from reputable developers and trusted sources.

Avoid pirated or modified premium software because it may contain malicious code.

3. Use Strong Administrator Passwords

Create unique passwords and avoid using easily guessed information.

Enable two-factor authentication where available.

4. Install an SSL Certificate

An SSL certificate helps protect information exchanged between your website and visitors.

Make sure your website uses HTTPS and that its certificate remains valid.

5. Maintain Regular Backups

Schedule automatic backups and periodically verify that they can actually be restored.

6. Monitor Website Performance

Check your website regularly for broken links, unusual loading delays, suspicious activities and unexpected changes.

7. Choose Reliable Hosting

Your hosting provider plays an important role in website performance, security and availability.

Choose a hosting plan that provides sufficient resources, backups, security features and responsive technical support.

14. A Practical WordPress Maintenance Checklist

Use this checklist to keep your website healthy and reduce the possibility of unexpected problems.

Daily Checks

  • Check whether your website is accessible.
  • Review important contact forms and business enquiries.
  • Look for suspicious website activity.

Weekly Checks

  • Check available WordPress updates.
  • Review backup completion.
  • Check important website pages.
  • Review website speed and functionality.

Monthly Checks

  • Review installed plugins and remove unnecessary ones.
  • Check your website security settings.
  • Test your backup restoration process.
  • Check broken links and outdated information.
  • Review website storage and hosting resources.
Your maintenance goal: Do not wait until your website develops a serious problem before paying attention to it. Consistent maintenance is one of the most effective ways to protect your online business.

15. Frequently Asked Questions About WordPress Errors

1. Will fixing a WordPress error delete my website content?

Not necessarily. Many WordPress errors are caused by plugins, themes, server configurations or temporary technical problems. Your posts, pages and database information may remain intact. However, always create a backup before attempting repairs.

2. Why is my WordPress website showing a blank white screen?

A blank screen may result from plugin conflicts, theme errors, PHP problems or insufficient memory. Start by checking recent changes and isolating potentially problematic plugins or themes.

3. Can I fix WordPress errors without technical knowledge?

Yes. Many common problems can be resolved through the WordPress dashboard or hosting control panel. However, database repairs, configuration changes and PHP troubleshooting may require professional assistance.

4. How often should I back up my WordPress website?

Backup frequency depends on how frequently your website changes. A business website with regular updates may benefit from daily backups, while a less frequently updated website may use a different schedule. Always maintain a recent backup before major changes.

5. Can a plugin damage my WordPress website?

An incompatible, poorly maintained or malicious plugin can create errors, security vulnerabilities or performance problems. Install plugins from trusted sources and keep them updated.

6. What should I do if my WordPress dashboard is inaccessible?

Check your login details, browser cookies, security restrictions and recent website changes. If necessary, use your hosting File Manager to investigate plugin or theme problems. Contact your hosting provider if you are unsure how to proceed.

7. Why is my WordPress website loading slowly?

Common causes include oversized images, excessive plugins, poor hosting resources, inefficient themes, database issues and unoptimized scripts. Website performance should be investigated systematically.

8. Should I reinstall WordPress when my website develops an error?

Not as your first solution. Reinstallation may introduce additional problems if important files or configurations are overwritten. Identify the cause, back up your website and attempt the appropriate repair first.

9. When should I contact a WordPress developer?

Contact a professional when an error involves database corruption, suspected malware, complicated server configurations, inaccessible website files or problems you cannot safely resolve.

10. Can my hosting provider help me fix WordPress errors?

Yes. Hosting providers can investigate server availability, database services, PHP configuration, resource limits and hosting-related errors. However, some plugin and theme problems may require a WordPress developer.

16. Final Thoughts: Protect Your Website Before Problems Occur

Your website is more than a collection of pages and images. It is an important digital asset that represents your business, communicates your services and helps potential customers discover your brand.
