BuddyPress.org

I am using bbpress along with buddypress in one of my wordpress website. Suddenly for the members pages it is showing “Invalid Options.”. I am not sure whether any changes done by the other admin or not as they are not sure as well. I have tried to search this in different forum but not able to get any such topic. Can any one help me out here?

Presently nothing is showing for the members pages but all other forum pages showing fine. For members pages it showing just a single text “Invalid Options” with out ant theme header or footer on a blank white page.

Thanks
