Well actually there are two TCs, syntax highlighting and line numbering that should act when I post code on my site, line numbering works but syntax highligting does not (only for that post)
And it seems that I wasn’t very clear when I made my request. I’ll try to rephrase it as best I can below. On my Discourse site, someone posted a message containing autolisp programming code. Normally, with the two components I have installed on my site, which are syntax highlighting and automatic line numbering, this code should be numbered automatically and the lisp language syntax should appear highlighted. This does not work, and I want to emphasize that it is only for this post, because it works for all the others. So only for this post, the line numbering works fine, in fact, I have never reported this problem. But the syntax highlighting does not work. I don’t know why this component theme does not work for this post only, and why it works for all the others.
