What happens to my private posts if I disable WP Sentry?
Because all of the posts are still listed as Private, WP Sentry is intended to be fail safe. If you disable WP Sentry or it stops working for any other reason, only site administrators should be unable to access your private posts.
Why don’t categories with private posts show up in the side bar?
This is a known issue with the default WordPress widget. I intend to re-write that widget at some point. The posts not appearing in the sidebar does not prevent them from being accessed.
Where do I send feature requests or bug reports?
Please email me (there’s a link in the sidebar) if you have anything at all to say about the plugin.
What’s the difference between ‘Allow All Registered Users’ and using a default user group?
These two features can behave very similarly, with one key difference. Users can be removed from the default group, making it possible for you to restrict access to posts allowed to those groups. This is not possible when selecting ‘Allow All Registered Users’. The only way to prevent a user from accessing one of those posts is to delete his or her user account.
