I'm using Confluence 4.2.8 on Server 2008. I'm using the Documentation theme for a space. I've disabled the Page Tree, but re-enabled it in the Navigation configuration using the pagetree macro ({pagetree:startDepth=2|searchBox=true}).
When I change the home page of the space to point to a specific page, the navigation tree is no longer displayed. When I change the home page back to the original home page, the navigation tree reappears. Is this a bug?
