Mysterious validation error

After the latest round of updates, I ran the lot through
First it came up with a missing </div> at the end of the page. When I added that, I got the following error.

  1. Line 280, Column 1: unclosed end-tag requires SHORTTAG YES
    The construct </foo<bar> is valid in HTML (it is an example of the rather obscure “Shorttags” feature) but its use is not recommended. In most cases, this is a typo that you will want to fix. If you really want to use shorttags, be aware that they are not well implemented by browsers.

However, there is a <body> in the line directly under </head>, and a </body> directly above </html> at the bottom of the page.
No typos that I can see, and I have even deleted both tags and retyped them. Nada.
??? :confused:

Where does the error message in the validator stem from?

Got it. Missing “>” on another tag. :blush:
