I've been flailing and reading, but not getting anywhere. If I take AF completely out, the forum topics and comments are all there and things seem normal (they just look terrible, hence why we use AF). Once I put AF in, I start getting:
You are not allowed to post new content in this forum.
WD: Warning: Invalid argument supplied for foreach() in forum_menu_local_tasks_alter() (line 179 of /home/hoslot5/public_html/modules/forum/forum.module).
Something to the effect of selecting the correct vocabulary in the settings, which i can't seem to find.
I'm in over my head.
