Failing to connect to database

Check what is the host of your MySQL user account.

If you have only one account like 'unityAdmin'@'127.0.0.1' this could be the issue. Create other account with privileges for 'unityAdmin'@localhost or update to 'unityAdmin'@'%'. Or, just update from 'localhost' to '127.0.0.1' in the database.php.

Thanks for the suggestions I will play with this now and get back to you. The user isn't the only user for the mysql account but it is the only user for the database I'm trying to use and setting the host to 127.0.0.1 in the database.php file changes nothing for me.

and $active_group = 'default';

This is already set as default so I didn't include it in the post sorry.
