We'll create fresh WordPress site with Restrict Media Library Access installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin restricts access for Authors and Contributors so they can only see their own Media Library uploads.
This has two main uses: Make it easier for Authors to locate their own uploads when Media Libraries grow very big and prevent Authors from using or downloading media that belongs to other users.
Admins and Editors will still be able to see everyone’s uploads.
