How to Fix the 10 Most Common WordPress Errors (404, 500, White Screen)

Encountering a fatal error on your WordPress site can be stressful, but 90% of issues stem from plugin conflicts, memory limits, or corrupted .htaccess files.

1. White Screen of Death (WSoD)

Enable debugging in wp-config.php by setting define('WP_DEBUG', true); to see the exact PHP line and plugin triggering the fatal crash.

2. Error Establishing a Database Connection

Verify that your DB_NAME, DB_USER, DB_PASSWORD, and DB_HOST match your cPanel MySQL database credentials exactly.

3. Fixing Broken 404 Permalinks

Navigate to Settings > Permalinks in your admin panel and click 'Save Changes' to instantly regenerate the rewrite rules in your .htaccess file.
