Please note:  When validating my site, I found that I was missing a closing div tag on all pages, regardless of content type or simplicity.  So, I think (though I could still be wrong) that it came not from something I'd put in place (like in a custom block or view) but from "MD TheNews."  After turning the site inside out and upside down, I found that the file "page.footer.inc" appeared to be missing a closing div tag.  Maybe it was missing that tag on purpose - but it appears as if it was actually a mistake.  Putting a closing div tag at the end of the file cleared up problems; afterwards the pages looked fine.  Proceed at your own risk - but this worked for me.  So far.
