Common WordPress Errors – WordPress is one of the most popular website platforms in the world, powering millions of sites. However, as with any software, WordPress users sometimes encounter errors that can disrupt their website’s performance. Whether you’re a seasoned WordPress user or a beginner, knowing how to troubleshoot common issues is crucial to maintaining a smooth-running site.

In this blog, we’ll cover 18 common WordPress errors and provide you with simple solutions to fix them.

1. White Screen of Death (WSOD)

Error: A blank screen with no error message, also known as the White Screen of Death, often leaves users stumped.

How To Fix It:

  • Disable Plugins: Access your site via FTP or cPanel, navigate to the wp-content folder, and rename the plugins folder to plugins-old to disable all plugins. If the site returns, enable plugins one by one to identify the culprit.
  • Switch Themes: Rename the active theme folder to disable it and force WordPress to revert to the default theme.
  • Increase PHP Memory Limit: Increase the memory by adding the following line to the wp-config.php file:
    define('WP_MEMORY_LIMIT', '256M');

2. Error Establishing Database Connection

Error: WordPress is unable to connect to the database.

How To Fix It:

  • Check Database Credentials: Ensure your wp-config.php file has the correct database name, username, and password.
  • Repair Database: Add the following line to wp-config.php:
    define('WP_ALLOW_REPAIR', true);

    Then visit http://yourwebsite.com/wp-admin/maint/repair.php to repair the database.

3. 404 Not Found Error

Error: The page or post you are trying to access returns a 404 error.

How To Fix It:

  • Flush Permalinks: Go to Settings > Permalinks and click “Save Changes” without making any changes. This resets your URL structure.
  • Check .htaccess File: Ensure your .htaccess file is configured correctly. You can regenerate it by resetting permalinks as mentioned above.

4. Internal Server Error (500 Error)

Error: A generic error that doesn’t provide specifics, but causes the site to break.

How To Fix It:

  • Increase PHP Memory Limit: As mentioned for the White Screen of Death, increase the PHP memory limit.
  • Check .htaccess File: A corrupt .htaccess file can trigger a 500 error. Rename it to .htaccess_old and refresh your site.
  • Deactivate Plugins: Sometimes, a plugin can conflict and cause this issue. Disable them one by one.

5. Connection Timed Out

Error: The server takes too long to respond, often due to heavy server load.

How To Fix It:

  • Deactivate Plugins & Themes: Try disabling unnecessary plugins or switching to a default theme.

6. 403 Forbidden Error

Error: You don’t have permission to access the page.

How To Fix It:

  • Contact Hosting Provider: If you’re unsure where the temp folder is, your hosting provider can help you fix this issue.

9. The Uploaded File Exceeds the Upload Max Filesize Directive

How To Fix It:

  • Increase File Upload Limit: Add the following lines to your wp-config.php or .htaccess file:
    define('WP_MAX_UPLOAD_SIZE', '64M');
  • Update php.ini: Alternatively, you can add the following to your php.ini file:
