Problem after moving server
 

We moved our forum from one server to another. Everything seemed to work just fine, until I tried to edit a user in the AdminCP.
Everything (not just user editing) I try to do, I get the following message:
"Forbidden
You don't have permission to access /forums/admincp/user.php on this server."

or

"Forbidden
You don't have permission to access /forums/admincp/adminpermissions.php on this server."

Or any *.php

In short, I cannot administer the forum.

Any idea as of what the problem may be?
Thanks!
Pat
