I had CB login module working fine. After I installed sh404, when user log in through CB login module, menu items that access to register users only do not show on the menu bar. If the users login through joomla login (from site offline), these menu items show fine.
I consulted with sh404, the problem consisted so I disable the plugin completely but still have the same problem.
Do you have any suggestion? I rather not restore a month old site backup if I don't have to.
