I am having the same issue. Logged out users are able to access content that only logged in user should see. Logged out users should not be able to see the directory of members. Not only can they still see the directory, they can see member types that are not supposed to be listed in the directory. (like the admin profile which should never show up) I have done a full conflict check, all plugins were turned off, and I used the default WP theme, but the problem persists.
