Dear W3C Validation Service,
This concerns . It has been validating as fully "green" for the past several months, but today every page returned this single error message:

Line 1, Column 1: end of document in prolog
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.o…

This error may appear when the validator receives an empty document. Please make sure that the document you are uploading is not empty, and report any discrepancy.

This is incredible, as my website pages are anything but "empty." I clicked on "Show Source" on your site, and it returned the entire HTML code of each page. So the site isn't even showing on your site as "empty." I have no idea what is going on here.
Please help me, as I need my website to validate. And thank you very much.
With the Warmest Regards,
