Database connection failed: Invalid username or password. Please follow these steps:\n1. Verify the MySQL root password (default installation usually has no password)
2. Check if the user 'admin_dbm2' exists in MySQL:
   - Log into MySQL as root
   - Run: SELECT user, host FROM mysql.user;
3. If the user doesn't exist, create it with:
   CREATE USER 'admin_dbm2'@'localhost' IDENTIFIED BY 'your_password';
   GRANT ALL PRIVILEGES ON .* TO 'admin_dbm2'@'localhost';
   FLUSH PRIVILEGES;
4. If you're using XAMPP/WAMP, check the default credentials in their configuration
