I can edit a user profile in the back end. But if I try and do it on the front end using the K2 User module, I get a 403 - Access Denied when I click save.

Lastest version of Joomla, K2.
CB not installed

I've searched the forums trying to find the answer - help would be appreciated!

so strange - only happening with the Super User account... (which is also in the same K2 user group as others who CAN edit their profile.)

So this isn't as urgent - but I'm really puzzled

The Super Users cannot edit their profiles from the front end.
Neither they can reset their password (Joomla!'s restrictions)
