Five days ago, I moved a page in our team's space from one Parent page to another Parent page. The original parent page has permission restrictions to a small management team. The new Parent page has no permission restrictions.
Once the page was moved, I verified with staff that the page was visible to all users of our space. Now, five days later, the page seems to have completely disappeared. Links to it return the attached error message (image).
There seems to be no trace of the page. It's not in anyone's activity list. It can't be found by the creator or last updated. Name searches return pages, but not the one we're concerned with. It is as if it never existed.
It's not in the Space Trash tab, not in the Orphaned Pages or Undefined Pages. It's a critical page to our upcoming project and we're hoping to not have to create it again.
Any ideas?
