Thanks Neil. I didn’t actually customize anything. V2 was working just fine along with WP-Member (http://wp-member.com/) but when I updated to V3 things started getting weird. If I disable, then re-enable The Events Calendar, the content from categories marked as Guest level via WP-Member appear to visitors that are not logged in (as it should), but as soon as I edit a post or category or event (while The Events Calendar is active) the Guest level content stops appearing to non-logged in visitors.
