Hi Guys,
Ive set up a category blog, with 3 K2 Items, i am wanting only registered users to be able to comment only on the items. So in the backend ive put the comments to registered users only. But when i go to the item on the frontend as a super user i can comment then i created a new account as a registered user and it wouldn't let me comment. Also my work mates are Super Users and they cant comment. Its only myself as a super user that can comment.

Any Ideas ??

Hi. What do you mean by you cannot comment? Are you getting any error? Or you just cannot see the form? Make sure that the user that is trying to comment is assigned to a K2 user group which have the appropriate permission.

I have this problem too. :(

Only owner can see comment form.
I set items Access level=special
and in:
"User Manager: Viewing Access Levels"
"manager" & "administrator" & "registered" selected for "special"
and in:
"Users Configuration"
"manager" & "administrator" & "registered" are full "Allowed"
what i must do?
THX

Yes, I had the same problem.
It solved by assigning the "Joomla User" to a "K2 User" group. You can create a K2 User group with the full rights and assign that to the super user of Joomla User.
