42Fears on "Error establishing a database connection"

I feel like I'm giving you guys too few elements on how to help me. So here's my wp-config.php :

// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'wordpress');

/** MySQL database username */
define('DB_USER', '[removed]');

/** MySQL database password */
define('DB_PASSWORD', '[removed]');

/** MySQL hostname */
define('DB_HOST', 'localhost');

/** Database Charset to use in creating database tables. */
define('DB_CHARSET', 'utf8');

/** The Database Collate type. Don't change this if in doubt. */
define('DB_COLLATE', '');
