I am working on some WP templates and I painstakingly (via Firefox's developer toolbar) made sure that each and every design (there are 12 now!) validated with the HTML validator.
I love to see that green "passed" text. I get a cheap thrill that way. Well, after I loaded all my themes, I decided to click the Valid XHTML button at the bottom of the page.
13 validation errors and they all had to do with an ID "Comments-Listing", which I could find NOWHERE in any of my templates.
Then just as quickly as it appeared (while I was revalidating all the themes), it vanished.
Any ideas what's causing this. I want to be able to click on that Valid XHTML button with confidence, and I want you to be able to also. Gah.
The site is here and you should be able to validate any of those themes.
