Error establishing a database connection

This either means that the username and password information in your wp-config.php file is incorrect or we can’t contact the database server at localhost. This could mean your host’s database server is down.

define(‘DB_NAME’, ‘DATABASE NAME’); // The name of the database
define(‘DB_USER’, ‘USERNAME’); // Your MySQL username
define(‘DB_PASSWORD’, ‘PASSWORD’); // …and password
define(‘DB_HOST’, ‘localhost’); // 99% chance you won’t need to change this value
define(‘DB_CHARSET’, ‘utf8’);
define(‘DB_COLLATE’, ”);

What are you supposed to put for the database name??

The directory on your hosting under which the blog is going, or the database thing provided with the MySQL account? I’ve tryed both and its still not working.
All help appreciated.
