I am also having problems getting these variables right. GoDaddy supplied a server name to use instead of localhost, and it does contain the user name. Even after plugging it in, I get a message:
"We were able to connect to the database server (which means your username and password is okay) but not able to select the VFC WordPress database.
Are you sure it exists?
Does the user vfcuser have permission to use the VFC WordPress database?
On some systems the name of your database is prefixed with your username, so it would be like username_VFC WordPress. Could that be the problem?"
// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'VFC WordPress');
/** MySQL database username */
define('DB_USER', '[username]');
/** MySQL database password */
define('DB_PASSWORD', '######');
/** MySQL hostname */
define('DB_HOST', '[username].db.7656751.hostedresource.com');
