Access Denied to Backend

Hi,

I’m having troubles to change the user-access role for WP-User-Avatar. Could you please tell me where I can change/add another user role to the actual admin-role. I’d need to add an ‘instructor’ role.

The problem happens in combination with

Thanks in advance.
Regards
Chris
