Hi, I am very new to silverstripe and I was just wondering how I can officially "log out" and see the website from a user's perspective. When I click "log out" now, I still see the "published site" square on the top right hand corner and the banner at the bottom (even when it says visitors cannot see it).
Try removing the variable $SilverStripeNavigator in your Page.ss template. This will remove that bar so you can see the page as it should be. However as you have clicked 'log out' then you should see the live site as a normal visitor.
