Sorry about missing latex files. I just updated the zip file and now there are
all there if you need them:


(I have script I run which cleans the build folder before zipping
and uploading to my webpage and it does this automatically).

I just did the changes you recommended (as root)

>diff tex4ht.sty tex4ht_ORIG.sty
< \gHAdvance\fstf:id  100000
> \gHAdvance\fstf:id  10000

And just started new build with max iteration set at 6 in the make4ht build file.

This will take about 1-2 days to complete.

Will update you once it is done. Hopefully this will fix all these problems
I was having and now all chapters and sections will show up.

Thanks again
