4. Reference the page title 'SOMETHING: Title'
5. Publish the page

The page tree fails to load with the error 'The selected root page could not be found.'

In server, the page tree will display if it is the root. Hhowever, if the page is imported to Cloud or moved the page tree will fail to display.

2. If the root page is the current page, use the @self value to list the root page with a colon.
