Hello!
I would like to change the registration, login, and profile design of CB. I've tried as suggested on an older post:
Joomla Backend -> Components -> Community Builder -> Configuration -> User Profile -> Template. If changing this does not render your PROFILE (this does not change your Joomla template) template any differently please try clearing browser and Joomla caches.
This does not seem to change anything (it also might have change since that time ^^)!
