...and it seems that I failed to install the Maps extension for my #MediaWiki installation successfully.
It shows up in my Special:Version page as installed:
https://wiki.sunkencastles.com/wiki/Special:Version
But when I actually try to use it, I get a fatal error.
Does anyone with experience with MediaWiki have a suggestion on how to proceed? Otherwise I might have to scrap this attempt and revert to a previous version.
