Maintaining a WordPress website involves regular updates and management tasks. However, users often encounter errors during maintenance routines that can disrupt website functionality. Understanding these common errors and their solutions can help keep your site running smoothly.

Common WordPress Maintenance Errors

1. Error Establishing Database Connection

This error occurs when WordPress cannot connect to the database. It can be caused by incorrect database credentials, a corrupted database, or server issues.

2. White Screen of Death

This blank white page indicates a PHP error, often due to plugin conflicts, theme issues, or exhausted PHP memory limits.

3. Internal Server Error (500)

This error suggests server-side problems, such as faulty plugins, corrupted .htaccess files, or server misconfigurations.

How to Fix Common Errors

Fixing Database Connection Errors

• Verify your database credentials in wp-config.php.
• Repair the database using phpMyAdmin or WordPress’s repair feature by adding define(‘WP_ALLOW_REPAIR’, true); to wp-config.php and visiting /wp-admin/maint/repair.php.
• Contact your hosting provider if the issue persists.

Resolving White Screen of Death

• Disable all plugins via FTP or cPanel to identify conflicts.
• Switch to a default theme like Twenty Twenty-Three.
• Increase PHP memory limit in wp-config.php by adding: define(‘WP_MEMORY_LIMIT’, ‘256M’);
• Enable debugging by adding define(‘WP_DEBUG’, true); to wp-config.php to identify errors.

Fixing Internal Server Error

• Rename the .htaccess file to disable it and see if the error resolves.
• Deactivate all plugins and reactivate them one by one.
