hi Michal,

It is allready in html4-math.4ht

>grep -i  cdnjs /usr/local/texlive/2018/texmf-dist/tex/generic/tex4ht/html4-math.4ht
\Configure{MathjaxSource}{https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/latest.js?config=TeX-AMS-MML_HTMLorMML}

I found why it does it now work on my end.

When I use my .cfg, the above line does not show in the HTML.

I did remove the old require mathjax-latex-4ht.sty from my .cfg.

But I think the reason is that my .cfg has additional mathjax
configurations I needed which you said to add it to .cfg before,
since I could not add it to mathjax-latex-4ht.sty. It uses
your

\ExplSyntaxOn
\regex_replace_all:nnN{ \x{23}\x{23}}{\x{23}}{\mymathjaxconf}
\ExplSyntaxOff

trick.

May be the order is now messed up from before when it worked?

Because I am doing additional MathJax.Hub.Config({ in my .cfg,
which does show in HTML, something now went wrong? This all worked
before. I need these additional fixes in my .cfg.

I am attaching my .cfg file. Can you please try on your end?

THis is how I called it

make4ht -c ./nma_mathjax.cfg foo1.tex "htm,mathjax"

Now mathjax do _not_ load in HTML, but when I do

make4ht foo1.tex "htm,mathjax"

Then it loads. Any work arounds?

Getting Mathjax to work is hard!

Thank you,
