When I deactivate BP Groups Extras and the forum topics are back in.
Yes ? didn’t notice that at all , will check it out now . 4ella is not running yet , I am not using it live yet, only testing it ,thanks for noticing . I will let you know here.
You are right , exactly how do you said , topics were gone , when deactivated there were back , I ‘ ve tried to create one topic ,when groups extras active and if you create new it remains so only previous topics created before groups extras installation were gone , thanks @Mikey3D for noticing that !
Really strange behaviour.
Will try to catch the problem
Yes strange , unfortunately it does exactly how mikey3d said , I had to deactivate it too , hope you will find an error soon to start to use it again.
I have this problem too!!!

Which BuddyPress version are you using?
I also have this problem and I guess I need to check what Buddy Press version I’m using. I’ll get back to you guys and hope you could help me.
