Can you specify the errors?
It's most likely that it's a problem on your end, and you're configuring something wrong, rather than it being a fault in the CMS itself.
Jeez, listen to what I said, It may be a problem with your database..., dont just skip half of the sentences, I had problems with the CMS due to the database, So try that..
There is a SQL problem but I think it may be fixed by editing the PHP code that I said above.
the vip_remove.php page has PHP errors in it, and because he obviously put it under the community tab it's coded in wrong and that's giving community_headers.php errors.
