Hi 

we recently migrated from on old standalone v6 instance( using the from pre8.sh) to 15.5.0 running on docker

I've recently been made aware that we can no longer see the history of wiki pages

Looking in the postrges database I can see a table for wiki_page_journals that looks as though it might contain the history; but it only contains id, author and text, so I am not sure how this might bind to any current pages

Does anyone have any suggestions?
