I have a small problem, maybe someone could please help me with.
In the CMS i have some pages added for example news, But some of these are in purple which I think means "hidden" but they still appear on the website. But I think they shouldnt be purple, how do I get it that it's a normal colour
Maybe have a look at the "Behaviour" tab of the page.
If "Show in menus?" is unchecked, the page appears hidden in the SiteTree. If you check it, log out and log in into your backend again, it should be black.
