SIte down, database error

http://test.sourcewestpartners.com

I was trying to move the url from the above subdirectory to the main url but have messed it up, I just want to get it back working again. I searched these forums already and have tried the methods here http://codex.wordpress.org/Changing_The_Site_URL but they have not worked for me. phpMyAdmin has not helped, the database appears to have the right url’s already, and editing fuctions.php did nothing either. I even tried restoring the database from a backup and had no luck there either.

I have no idea what to do.
