How to enable code snippet syntax highlighting?

[KnickKnack]

Good morning community,

I'm running nodeBB 1.9.3 and I can't succeed in getting code snippet syntax highlighting in my instance.

As you can see below using ```ruby on the code snippet "opening" works fine. On my instance instead highlighting doesn't seem to work at all. What could be the cause? Where can i look into?

require 'redcarpet'
markdown = Redcarpet.new("Hello World!")
puts markdown.to_html

This is how my code highlighting box looks like:

No ideas community? No hints on what could be the cause and eventually what to check?

@KnickKnack Shouldn't Automatically detect and highlight code blocks be checked?

Hi @baris, thanks so much.

I didn't checked it out since I thought it was only enabling automatic syntax detection and not highlighting, but after checking it I got highlighting out of the box for free
