Tim Nafziger commented on How do I change which page is my home page?
One important piece that is missing in this official response is that once you have clicked the check box to make a the home page, it disappears from the page settings page. In other words there is no way to immediately unset from the same page once it has been set. In order to stop having a page be the home page for your site (or UNset it), you have to go to a new (or old) page that you want to make the home page and check the box on that page.
