[Theme: Frisco for BuddyPress] Logout out error

I’m super new with BP and Frisco. So your patience is very very much appreciated.

Whenever I tried to logout of backend, I get a blank page and the url reads https://www.mydomain.com/wp-login.php?action=logout&_wpnonce=%5Bsome code]

I backed page to the backend and deactivated ‘BP Adminbar for Admins Only’ plugin, the only BP plugin I have installed and activated after BP and Frisco, I can then logout normally. So is it the theme or the plugin that is causing the problem. What should I do?

Thanks very much for your patience and this is the only decent theme I like very much from the rest of the BP compatible themes. I’d like to use it extensively for my future community sites for sure. ??
