WordPress errors can be frustrating, but most have straightforward fixes. Here are some of the most common WordPress errors and how to resolve them:

1. White Screen of Death (WSOD)

Cause: Plugin/theme conflicts, memory limits, or corrupted files.
Fix:

• Disable all plugins via FTP by renaming the plugins folder (wp-content/plugins).
• Switch to a default theme (e.g., twentytwentyone).
• Increase PHP memory limit by adding this line to wp-config.php:

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

• Enable debugging (wp-config.php):

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

2. Error Establishing Database Connection

Cause: Incorrect database credentials, corrupted database, or database server issues.
Fix:

• Check wp-config.php for correct database details (DB_NAME, DB_USER, DB_PASSWORD, DB_HOST).
• Repair the database via wp-config.php by adding:

  define('WP_ALLOW_REPAIR', true);
  

• Contact the hosting provider to check the database server.

3. 404 Page Not Found Error

Cause: Broken permalinks.
Fix:

• Go to Settings → Permalinks, then click “Save Changes” to regenerate .htaccess.
• Manually reset .htaccess:

  # BEGIN WordPress
  RewriteEngine On
  RewriteBase /
  RewriteRule ^index\.php$ - [L]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule . /index.php [L]
  # END WordPress
  

4. 500 Internal Server Error

Cause: Plugin/theme conflicts, memory issues, corrupted .htaccess.
Fix:

• Rename .htaccess to .htaccess_old and refresh the site.
• Increase PHP memory limit (wp-config.php).
• Deactivate all plugins and switch themes.

5. Stuck in Maintenance Mode

Cause: Interrupted update process.
Fix:

• Delete the .maintenance file from your root directory via FTP.

6. Too Many Redirects

Cause: Misconfigured siteurl or home settings.
Fix:

• Define correct URLs in wp-config.php:

  define('WP_HOME', 'https://example.com');
  define('WP_SITEURL', 'https://example.com');
  

• Clear browser cache and cookies.

7. WordPress Not Sending Emails

Cause: Hosting email settings or PHP mail function disabled.
Fix:

• Install an SMTP plugin like WP Mail SMTP and configure it with a third-party SMTP service (Gmail, SendGrid).

8. Login Page Redirect Loop

Cause: Corrupt cookies, plugin conflicts, incorrect URL settings.
Fix:

• Clear cookies and cache.
• Disable .htaccess and regenerate permalinks.
• Check database for correct siteurl and home values (wp_options table).

9. Allowed Memory Size Exhausted

Cause: Not enough PHP memory.
Fix:

• Increase memory limit in wp-config.php:

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

• If that doesn’t work, ask your hosting provider to increase it.

10. Missing Stylesheet Error (Theme Installation)

Cause: Incorrect theme file structure.
Fix:

• Ensure you are uploading the correct ZIP file. The main ZIP file from ThemeForest or other sources may contain extra files—extract it and upload only the theme folder.
