[Plugin: BuddyPress Wiki Component] Cannot Delete Pages, Admin vanishes if you change group properti

If you change the group settings after installing this component the admin panel (groups tab) vanishes and cannot be restored. The delete pages link also disappears. Also, deleting pages in the custom post types (where pages are created) has no effect. After waiting two weeks for any response from anyone in the forum I’ll assume this project is abandoned. If these weren’t critical errors I’d have rated otherwise.
