Hey Pagelines team! We are unable to get the sidebar to disappear on our posts page. Here is a live example: http://test.joychurchinternational.org/?page_id=496 And here is a SS of the settings: http://test.joychurchinternational.org/wp-content/uploads/2010/08/47EB2F6E519E96C5.jpg and here: http://test.joychurchinternational.org/wp-content/uploads/2010/08/39AA7049D95826DE.jpg Is there a way to get rid of the sidebar on the blog post page? Thanks for all of your help!!
