My best guess is that either:
* The SCLogin module is set to display to Guest users only and not to Registered (logged in) ones.
* In the Logout View settings area of the SCLogin module, the "Show Logout" setting is "Hide"
* The module position doesn't display when a user is logged in. Some templates have "Guest only" module positions that are meant specifically for login type areas.
Test that out to see if it helps, but if not, please create a test account we can use (test / test) and we'll gladly see what we can do to help.
Thanks,
Alex
