Thanks for the feedback. Emailed the screenshots and some additional info. I have an author role and an Author Admin role (so one author can edit the posts of specific other authors). All of that is set via the content restriction options in the URE Pro plugin.
I also have some code to limit the media to only the user uploads OR the users the author admin can edit (switching this code off doesn’t make a difference).
In the latest version of the URE Plugin, the media library is blank for the author admins. If I downgrade the plugin to 4.7 via ftp, everything works and the media is shown.
P.S. My Author Admin role is a copy of the Author role with “edit_others_posts” as the only additional option.
