Hi everybody,
When I switch on usual Joomla! user's Login Form, it works normal.
Then I switch it off, switch on Community Builder Login Form. It works but doesn't send any letters for new users registration process.
Please tell how to drive it.

Please check your CB configuration -> registration panel. Post the settings in there if your problem still exists.

Uninstall-install of CB helped.
I tried to find but didn't in Configuration.

Thanks.
