Ok, thanks, so let's try to solve each problem separately. Please find
attach a simple example of split environment. The tex-file is ok, but
make4 -a debug split_ex.tex gives the error message
=========
! Package amsmath Error: \begin{split} won't work here.
See the amsmath package documentation for explanation.
Type H <return> for immediate help.
...
l.21 \end{split}
=========
The full log file is also attached.
Can you please have a look? Any hint is appreciated.
Thanks a lot,
best regards, Tomas

Hello,
I made several tests with tex4ht. The tool nicely converts most of
the objects/environments, but I noticed two problems:
1. split environment
I use that for typesetting long formulas, for instance
This is my very long formula
\begin{displaymath}
\begin{split}
\tau(\eta^0) & = \frac{\hbar}{\Gamma(\eta^0)} =
\frac{\hbar c}{c \Gamma(\eta^0)} =
\frac{0{,}197~\gev\cdot\mathrm{fm}}{3\cdot
10^{8}~\mathrm{m}\cdot\mathrm{s}^{-1}\times
1{,}30~\mathrm{keV}}
= \\
& = \frac{0{,}197\cdot 10^{-15}~\gev\cdot\mathrm{m}}{3\cdot
10^{8}~\mathrm{m}\cdot\mathrm{s}^{-1}\times 1{,}30\cdot
10^{-6}~\mathrm{GeV} = % \nonumber\\
0{,}0505\cdot 10^{-17}~\mathrm{s} = 5{,}05\cdot
10^{-19}~\mathrm{s} % \nonumber
\end{split}
\end{displaymath}
This works perfectly in pdflatex, but when running htlatex, I get the
following error message:
It would be better to show a complete self contained example, not math
fragment.
And the complete commands you used to compile. This way no one have to
guess.
It is also better to use make4ht not htlatex. make4ht is now
the standard way to compile latex to HTML.
