I created a user group that has full permissions for User options in the CP, i.e. all the boxed ticked. However, they are not able to edit a user's email address.
When changing the email field and clicking Save it asks for password as usual, accepts it and closes the user form. However, the email does not change and there is no error message.
If I go in as Admin, it works fine, but not for any User Group, irrespective of the fact that their permissions include changing email addresses.
One possible clue is that these users were migrated from an older site and the email addresses have not yet been confirmed. Any thoughts would be appreciated!
