Thanks @inspirationnally I did the same thing for now. But as you said I actually wanted to not show them at all. I tried playing with the tehnik_bpp_filter_forums_by_permissions func without luck. Do you think this could be easily fixed plugin-side?
Also be warned they can still enter the post url and see them (it’s fixed only in their GIT repo) and also they come out in searches (not fixed yet, but a quickfix is available in their bugtrack as a comment).
Anyway i didn’t notice the Kalice reply above, I’ll try something later and post a fix if working.
