Hello,
I have an installation with 2.1.2+build.2017.05.04.16.30.55.c67734e1f and Joomla (3.7.0).
I have a menu item that is a Community Builder -> cb profile.
I log into the frontend with the CB Login module and enter the cb profile menu.
I always get a message (banner) saying I am not authorized.
Even with this message, the profile works fine.
Maybe there is some issue regarding CB's integraton with Joomla?
