Having the same problem. The other day I created a page, did not put it in any resource group and assigned it some template variables that we take the values of like so to make them appear on other pages:
[[getResourceField? &id=`165` &field=`beanfieldInternet` &processTV=`1`]]
I'm a super user and I cannot find document 165. Cleared cache in system and manually, flushed permissions, flushed sessions. Still no luck.
Where would I look in the database for this document?
The solution "I actually just found the problem. The pages had been assigned to each other as parents." doesn't explain how this was discovered. Are there any more details?
The only thing installed since we created this document was 2.2.8.
