UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 6 Support Forum can't posting and control panel can't login in su

The website is http://www.neilpryde.com/forum/index.php

My Forum version is UBB.classic 6.3.1.1

The forum can't posting and login suddenly.
The control panel also can't login. I try to retore our backup tape. But the forum doesn't work.What wrong is it????

in my completely not-expert opinion, something seems to be causing a problem with the post method.

*disappears so someone who knows what they are talking about can help*

Can you provide a direct link to your ultimatebb.cgi
Can you provide the exact error message(s) you receive when trying to login.

he gets no error, it just goes to the forum summary. Tried with and without the frames, the GET method works, but the POST method doesn't

That almost sounds like an Apache problem. You should consult your host to fix the POST.
