Greetings, all:
Specs...
Joomla 1.6.0; PHP 5.2.17; linux/apache on GoDaddy; CB 1.4; Joomla and CB both very recent clean installs with only Kunena as a noteworthy additional extension added thus far.
The User Manager menu is showing all users as merely 'public' including super users and users who were defined as joomla managers, etc. No custom user groups have been created. While logged-in in the joomla back end as the super-user, any attempt to edit any user in CB User Manager (including myself) results in the "You cannot edit a `public`. Only higher-level users have this power." message.
Also, CB User -> New -> Contact Info -> Group: only shows 'public' as an option if that helps. I looked at some of the other topics with that message, but this differs from the very recent topic titled with that error message in that in our issue no user has ever been able to edit any other user in our installation rather than just certain groups.
All the 'Tools' result in green across the board, I have reinstalled CB from a fresh download overtop the first install, and tried as many of the "H.U.H.Y." suggestions as possible.
So I place my plea and my offering of oreos and mountain dew at the feet of the IT gods for assistance.
