HTTP 500 Internal Server Error

Okay I’m now and I thinked I’ve screwed up because the installation has gone funny.

What do I have to put in all of the following:

define(‘DB_NAME’, ‘ ‘); // The name of the database – is this my provider?
define(‘DB_USER’, ”); // Your MySQL username – know this
define(‘DB_PASSWORD’, ”); // …and password – and this
define(‘DB_HOST’, ”); // 99% chance you won’t need to change this value – is this my ftp?
define(‘DB_CHARSET’, ‘utf8’);
define(‘DB_COLLATE’, ”);

Sorry to be a hassle.
