BuddyPress.org

Hi,
I have a big Problem.
I used the BuddyPress Version 10.2.0 Plugin in combination whith Ultimate Member Version 2.3.2 and bbPress Version 2.6.9. I think this combination is a little bit difficult but it finaly worked well.

I just changed some settings in the BuddyPress and then i got this Error:
