I am testing rtMedia on a new site I am developing with WordPress & BuddyPress. I have Privacy enabled for rtMedia and set to “Logged in Users - Visible to registered users”, however when you visit the site as an unregistered user and go to the member directory you can view the rtMedia photos for a user, even though they should be private.
Please check rtMedia with WordPress default theme and with other plugins disabled. It might be theme issue or plugin conflict.
