We are running UBB.threads 6.5.5 and recently had a security problem (hacker). We were able to stop the intrusion before it got too bad but in an effort to cover his tracks the hacker deleted everything on the system with the word "log" in the file name.

Two of those files were ubb.thread's login.php and logout.php which have since been restored. However we still can't login or logout.

Any one have suggestions on how this can be fixed?

Thanks,

David Gentry
