Syntax Highlighter not working on shopify theme editor

It is all plain black now. Even shortcuts are not working. I tried different browsers and different sites. All highlighters don’t work. It is like righting on a notepad now.

I am having the same issue, but only with *.liquid files. All plain black text.
Any help is appreciated

I have contacted their chat support and the one I have talked needed to forward it to higher support because she cannot solve it so I am waiting for the email about it.

Today my code editor is highlighting well. It should have been something temporary.

Thanks!

Yeah, same here. Maybe they were just updating something.

This is happening to me now. 22.04.2026
.css , .json etc file are all correctly displaying with colour highlights.
But all the .liquid files are just plain black text.
