A "Database Connection Failed" or "500 Internal Server Error" usually indicates that your application cannot communicate with its MySQL database. Before logging an Urgent support ticket, please verify the following common issues:
1. Check Your Database Credentials
If you recently migrated servers or changed passwords, your application configuration may be outdated. Open your core config.php file and verify that the DB_HOST, DB_USER, DB_PASS, and DB_NAME perfectly match your current database environment.
2. Verify the MySQL Service is Running
If you manage your own VPS or Local AMPPS environment, verify that the MySQL/MariaDB service has not crashed. Restart the database service from your control panel.
3. Check User Privileges
Ensure that the database user assigned to your application has been granted full privileges (SELECT, INSERT, UPDATE, DELETE) to the specific application database.
If you have verified these three steps and are still experiencing a connection failure, please log a support ticket and include any recent changes made to your server environment.
