Can't access usergroup manager in AdminCP anymore
 

Hello,

For several weeks now, I have been unable to access the four first entries in the "Usergroups" tab in AdminCP anymore - basically all links that refer to /usergroup.php are dead.

I tried it on several browsers from several computers, but all these four entries only bring up a white page in the AdminCP frame without even so much as an error message.

Any help here would be tremendously appreciated!

Thanks, Tobias

Check your error_logs - I'll bet the error shows up in there.

Download a new fresh copy of the version of vbulletin that you are running and reupload the pages in your admin cp and mod cp.

Thanks! Do you think it would be enough to simply reupload the usergroup.php?

Maybe, maybe not. The usergroups.php page probably relies on other files also - so it could be one of the other files causing the problem.
