I tried giving the new role I created (Media Editors) the delete_posts capability and it didn’t help.
I’ve got all my users set as Subscribers as default. I’m using Press Permit Core to then permission out the ability to edit certain pages and all their children pages. Press Permit Core then makes them Editors of those specific pages. I tried giving them an additional role as Media Editor with all Media options ticked and delete_posts unticked.
Is there anything that might be going wrong there?
