Major K2 Joomla user problem...

 

I have a clean install of Joomla 1.5.22 with Joomlart's Teline IV and K2.

 

The only user that can log in in the backend is the original administrator. All others report "You do not have access to the administrator section of this site." I created new users in the normal user manager but they do not show up in the list after saving. However, they DO show up in the K2 users tab. They appear as Super Administrators and even after adding them to a K2 group, the user cannot log in from the back end. When I create users in the K2 component, the same thing is true. I can edit the users via the K2 users tabs, changing the password, access level, etc., but they still are missing in the core joomla user manager and still no logins allowed. Still only ONE user appears in the core User Manager list...the original Super Admin.  

 

This renders the site completely useless since only one person can log on.
