There are three steps you need to follow when restricting page access for users:
1. Whilst editing the applicable page, click on the "Access Control" bar [Admin: Editing a Page under Page Manger]
2. Choose the variable setting and either "Update" or "Add" the page. [Admin: Editing a Page under Page Manger]
3. Remember to test the variable setting you selected, so that you make sure the right user group, or login state can or cannot view the page.
