Re: bb-admin: Forums Not Displaying
That’s a lot of plugins. Since I’ve never heard of or seen this problem, my guess is that it’s plugin related. Even people who’ve integrated with WordPress have never described the problem you’re having.
I wouldn’t disable them all. I think I would try disabling any that affect the data you see in the back end. I’m not familiar with all those plugins so I am unsure which ones affect the back end.
But, worst case, yes, disable all plugins and see if you can see the forum list. I don’t think a front end theme would affect what you’re seeing or not seeing in the back end.
