Hi Christopher,

This is working well, but I wish we could allow Editors to EDIT the profiles as well. The thing is that if we provide them the 'edit_users' capabilities, they can modify admin profiles too... and we don't want that.

I can't find a way to sort this out. How would you hide non-subscribers profiles to the editors ? I posted this question on http://wordpress.org/support/topic/editors-can-only-edit-subscribers-profiles, but I thought you could eventually sort me out here.

Have a nice day !

WebMaestroFr, you can prevent the Editor from accessing the "admin" user.php and user-edit.php pages.

Great..
