I installed the BuddyPress Profile Visibility Manager plugin. I have checked “no” on the Do not hide users from site admin? Now when I log in as the admin on the account, I have gone to my profile within the website (the front end and NOT the back end) and set myself up as hidden for everything. I have also done this for another admin on the website. When I view the “activity” page (on the front end and NOT the backend), I can see both myself and the other admin’s member profile. According to the plugin instructions, this is not supposed to happen as both admins are not to be seen on the website even while logged in as an admin.
