Broken rootline. Mountpoint parameter does not match the actual rootline. mount_pid (xxx) does not match page uid (yyy).
Check your realurl data¶
When I encountered this problem the reason was an invalid entry in the ID to path mapping of realurl.
The problematic data was inside the page with the UID shown in yyy in the above example of the error message.
I cleared the ID to path mappings in the yyy page and the problem disappeared.
