Hi!
I've just ran a fresh install of the CB and ran the installation steps from documentation.
Everything works fine CB login, registration and so on.

But everything on my web site must be private. Thus to avoid module display etc I simply put my home page (default joomla) with a "registered" access level.

Here comes the issue:
however the login module is disable, the page that comes up is the default com_user joomla Login and registration page!
see: my web site home

Can you please tell me why? or explain how to make sure the CB login screen is the default?

There is a redirect plugin on the JED that can be used.

bye

Excellent!
thanks a ton.
