I'm trying to create a second super user for my homepage. Creating a user with lower permissions like Registered works just fine. But all Users with backend access create a 403 error in the Joomla backend and won't let me create such a user.
I upgraded the page from Joomla 2.5. to 3.3.6 using the regular procedure.
Might it be possible that Admin Tool prevents me from creating a second super user?
Thanks
Roger
