Database connection failed: SQLSTATE[28000] [1045] Access denied for user 'ikeypro_test'@'localhost' (using password: YES)

Fix: Create or edit config/database.local.php on your server with your real DB credentials:
  define('DB_HOST', 'localhost');
  define('DB_USER', 'your_cpanel_db_user');
  define('DB_PASS', 'your_password');
  define('DB_NAME', 'your_cpanel_db_name');
This file is never overwritten by updates. Copy from config/database.local.example if needed.
