Yeah, that seems to be a bug in the legacy Markup Validator (that is,
https://validator.w3.org/)

I have no idea how to troubleshoot it. But the fix is just to not use the
legacy Markup Validator but instead to just use the current W3C HTML
Checker (https://validator.w3.org/nu/).

Yeah https://validator.w3.org/nu/?doc=3Dhttp://www.mdsupplies.com works as
expected, and that=E2=80=99s the recommended tool to use.

There is no problem with the response. You can verify that by doing this:

  curl -s -H "Accept-Encoding: gzip" http://www.mdsupplies.com | gunzip -t

Which as expected returns nothing (indicating there=E2=80=99s no gzip error=
).
