Thanks you for your response,
I had posted it on WP.org as well — or so I thought — but now I cannot find it.
The only two plug ins that I had on the site were Akismet, and something called Hello Dolly which was there from the beginning but inactive. I just deleted Hello Dolly, but it has not affected the validation.
I do use a stock theme, Fighter, but it was modified by the person who customized the fonts, etc. to match my main website.
Any additional help would be greatly appreciated. I will also post it again on WP.org.
