I have numerous K2 users that need to be able to edit ONLY their Personal Details and their Contact Details. Can some kind K2er point me to the file that I can adjust to my needs?
(I do have subtemplates in place.)

I will share the relevant user login upon their response to this message.

Create a k2 user group "registared" and set the permission for that group.....with no editing allowed
Set this group to be the default group new users are put in.
These users will be able to edit their profiles and their pages, but will not be allowed to add or edit other content
