Wait wait wait – why are you deleting buddypress? I dont’ understand.
Either way if you follow the instructions to create a new forum then you are able to see your forums and click Post New Topic then you’re doing it right so far.
If you’re getting that bug there is a fix that seems to work for me, I found it on the site:
You have to go to group admin settings where you turn on/off forums for that group.
You need to check/un-check the box a few times to ‘massage’ the form into actually tuning it on. Yes I know it sounds retarded but it’s true. You click and unclick that selection box about 4 times and then save. You should be good to go.
