Hi everyone a client of mine is having a problem with his admin modul. He claims he was browsing the sentinel block and only typed in his email address, then the site booted him. Everytime I try to access his admin panel (ffa.noblecomputing.com/admin.php) it prompts me with a form to type in username/pass.

"Enter Username and Password for "Protected" at ffa.noblecomputing.com"

This is what is says in the form prompting me for Username/Pass. When I try to type in any admins name/pass it tells me "leave this site now" I tried the GOD ADMIN of the site but that didn't work either. Help is much appriciated.
http://ffa.noblecomputing.com is the site
