I'm running XOOPS 2.2.4 with CBB 2.32 and the forum module is not working correctly. I've read elsewhere that the CBB module might have conflicts with WordPress, so I deactivated that module. This did not help either.

Here's the site I'm currently working on:
http://winnacunnetfoundation.org/newsite/modules/newbb/

As you can see, when you click on the "Forum Test", the following error appears:

Fatal error: Call to a member function on a non-object in /home/content/f/o/w/fowfadmin/html/newsite/modules/newbb/viewforum.php on line 95

There is only one way I can view the default post, and that is to go to "Main Options" --> View All Posts, but obviously I don't want to do that everytime I go on the forum.

I have tried using NewBB2, CBB 1.16, CBB 3.0, you name it. However, they all give me the same exact error. I'm truly stumped, please help.

I am haveing the exact same problem. Anybody got a answer for this?
