I think I figured it out thanks to your suggestion before. The page is now rendering OK for basic usage.
Still don’t understand how the rewrite rules work, but I am getting there I think

What is not working is the Visual editor which is throwing an error:

I cannot really see anything wrong in the actual URL’s requested. They look the same on the live server as on this. But for some reason the Visual editor is not working. Perhaps it is using some socket connection not working through the reverse_proxy bit?
Caddy: https://wikidev.tnonline.net/w/Main_Page?veaction=edit
Apache: https://wiki.tnonline.net/w/Main_Page?veaction=edit
It may be a MediaWiki configuration error, but hard to tell. The codebase is identical between the Apache and Caddy setup. I’ll check with the guys over at #mediawiki to see if they have any ideas here.
