Thanks. Yes, I had code inside the Latex file itself, not my .cfg,
as follows

======================
\ifdefined\HCode
Here is the animation from the Maple notebook:

\ScriptEnv{html}
    {\NoFonts\hfill\break}
    {\EndNoFonts}
   
   \HCode{
   <p><IMG SRC="movies/movie.gif" ALT="some text" WIDTH=750></p>
   }
\fi
=======================

I'll fix it now to remove those p's. The above is old code. But
the warning is new, which is good.

That was my own error actually. I fixed it. I had extra stuff
there.

btw, I noticed something while fixing the url.

Before, I had this (this is old file, I did not know about \url then)

            \href{http://...}{\nolinkurl{http://...}}

I now changed it to

           \url{http://...}

But the HTML in the first case shows an EXTRA space in the first
example above after the http:// compared to second example above.
(please see screen shot attached)

Both links work though. It is just strange why the first one has extra space
there.

I attach this small Latex file if you like to try it and see for yourself.
It is not a big deal, as link works and I do not use \nolinkurl anymore,
changing everything to \url{} now.

The command  I used to compile the attached file is

make4ht -ulm default -a debug foo5.tex "mathjax,htm"
