This often happens if a shortcut within your rootline points to some 
non-existing page.
Example: 'home' is a shortcut to 'news' subpage, all pages are arranged 
as subpages of 'home', but the target 'news' page was deleted, or access 
rights on targets of shortcut pages are incorrect -> any access to a 
subpage of 'home' will show this rootline error.
Hint: If this is the case, try to use 'first subpage' as shortcut 
target, this could prevent some of those cases.
