As standard MathJax does not display error messages.
Thanks to post by mpaw and MathJax documentation I figured out how to add it to the configuration. I changed overall_footer_after.html to the following:
Code: Select all
<script type="text/javascript" async src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.7/latest.js?config=TeX-MML-AM_CHTML"></script>
<script type="text/x-mathjax-config">
MathJax.Hub.Config({
TeX: { noErrors: { disabled: true } }
});
</script>
