Thanks for the suggestion, but...
Nothing has changed in the ubbthreads folders -- and all files seem perfectly intact; we've just suddenly lost functionality that used to be just fine! This is affecting all admin accounts on all installations of ubbthreads on our boards server, so is unlikely to be caused by file corruption. All that seems to be affected is access to the admin area and also the ability to logout, which also seems to be denied to admins!
Any help gratefully received, as currently no-one can get in to approve a large bunch of new boards members.
