Thanks Michal.

I overwrote

/usr/local/texlive/2018/texmf-dist/tex/generic/tex4ht/latex.4ht

with the file you attached and now make4ht foo1.tex "htm,mathjax" using
the example latex I posted in my last email does _not_ give an error
any more.

But I found another syntax error testing it more.

This MWE

=====================================
\documentclass[12pt]{article}
\usepackage{graphicx}
\usepackage{amsmath}

\begin{document}

\begin{align*}
\overrightarrow{\sum}F_x  &= Mx'' \\
F(t) -kx -H               &= Mx'' \tag{1}%
\end{align*}

\end{document}
=========================================

Gives an error compiling using make4ht foo1.tex "htm,mathjax"

=====================
(/usr/local/texlive/2018/texmf-dist/tex/generic/tex4ht/html4-math.4ht)
(/usr/local/texlive/2018/texmf-dist/tex/generic/tex4ht/html5.4ht)) (./foo1.aux)
! Misplaced \cr.
\math at cr@@@ ->\cr

l.11 \end{align*}

? x
==================

It compiles OK using  make4ht foo1.tex "htm" and compiles OK
with lualatex and compiles OK with SVG for math. Only in mathjax
mode it gives error.

Any idea why this now fails in mathjax mode? I am sure this
compiled OK  in mathjax before the latest updates.

Thank you for your help.
