Well, looking at the errors your site is showing it seems that it is having trouble loading the links from the database as well as (possibly) the template file.

As far as this being a script exploit, the only place an exploit file could have been uploaded is from the Admin CP (which requires admin access) and even if they could get a .php file uploaded to the picuploads/gif or picuploads/jpg folder it would almost certainly not execute as the .htaccess file in the gif and jpg folders turns off PHP for that directory (if your server supports this) and also forbids file access to files with .php extensions so anyone attempting to access them would get a 403 forbidden error.

Do you have any more details as to what happened?

Did you ever post your username / password in the public forums when seeking support and never remove or change them?
