Thank you all for the suggestions. The theme is Atahualpa 3.5.3. I renamed the theme, but still not work. However, I haven’t tried resetting the theme or plugins from database.
Hugo,
I am not sure whether I understand “You need to visit the themes page to ensure you have reset themes before logging out or trying to visit the frontend as the BP theme was still in effect operational in WP eye’s” correctly. Do you mean “when I disable buddypress, I need to go to my site’s front page, then log out”?
