I am currently using Joomla 1.6 and CB 1.4 (recently updated from 1.6 RC and CB1.3.1)
I created a userlist to show all users since we are using it as a contact list.
If I login on my user account (super admin) I can see the list, but if I click on any of the users with the exception of my own name I get the message: "You are not authorized to view this page!". I have no problem checking my own account.
However if I login via a different account who is just a registered user I am actually able to open all the users on that list. I am using the CB login module
So I think it has to due with a weird setting on my behalf.
These are the settings I have for the list:
User Group to allow access to: Everybody (tried registered users, but that didn't fix the problem)
User Groups to Include in List: selected everybody
hotlinking protection is turned off.
