🛠️ Troubleshooting & Error Solutions
🔴 How to Fix "Error Establishing a Database Connection"?
Direct Answer: The "Error Establishing a Database Connection" error occurs when wp-config.php credentials (DB_NAME, DB_USER, DB_PASSWORD) do not match MySQL database settings or when the database service is unresponsive.
Fix Steps: Open wp-config.php via cPanel File Manager and match DB_NAME, DB_USER, and DB_PASSWORD with your cPanel MySQL Databases menu credentials.
🟡 How to Fix WordPress 500 Internal Server Error?
Direct Answer: HTTP Error 500 in WordPress is typically caused by exhausted PHP memory_limit, faulty plugin updates, or corrupted .htaccess rewrite rules.
Real-World Scenario Diagnosis: If 500 occurred immediately after a plugin update, rename that plugin folder in wp-content/plugins via cPanel File Manager to disable it. Increase memory_limit to 512M in cPanel Select PHP Version > Options. If unresolved, rename .htaccess to .htaccess_old to reset rules.
🔵 How to Resolve 404 Not Found on Inner Pages?
Direct Answer: If the homepage opens but inner pages throw 404 errors, WordPress Permalink rewrite rules are missing from the .htaccess file.
Fix Steps: Log into WordPress Admin Dashboard > Settings > Permalinks and click Save Changes without altering any fields to regenerate the rewrite rules.
