The database isn't working

[eluser]InsiteFX[/eluser]
./application/config/database.php

Code:

$db['default']['hostname'] = 'localhost';
$db['default']['username'] = 'user_login';
$db['default']['password'] = 'user_password';
$db['default']['database'] = 'your_database_name';

If these are correct then you must not have started the mySQL database server
