After registering via CBSubs, my members are unable to login. For some reason, the button to view the profile is amended with "&task=registers&itemid=3" after "?option=com_profiler". The problem is the "&task=registers", as they get an error message saying "you are already logged in". If they navigate to any other page (that has a menu item other than 'Register'), they can then log in.

How do I fix this?
