Hi there. I have a network on which several different clients have their own WP install (as part of a WP multisite I made of course). Since they are separate clients I don't want them to see each other's content via their WP CMS. Obviously by default they can't see each other's images, articles or posts. However, they can see each other's themes if they access the themes selection screen (Appearance -> Themes). Is there any way to fix this so that each WP website on my multisite will only see the themes that were installed or created in it?
Thanks in advance for your time.
