Thanks, hugofreak. I disabled CalPress Calendar, and now everything is OK. If you visit the CalPress Pro website, calpresspro.com, their site is throwing the same error (at least as of 2 Aug 2013, 3:45 pm EDT).
Validation is important to someone like me, building a site for a program sponsored by a US government agency. The agency requires that the site meet accessibility and XHTML 1.0 transitional standards and pass the WC3 Validator.
This page

gets eight W3C Validator errors. Errors include:
— form tag must have an “action” attribute.
— input type=”email” isn’t recognized.
— text area requires rows and columns values.
— the “vfb-item-secret” list item has no closing “/li” tag.
— the “vfb-item-submit” list item and “vfb-submit” input use the same ID.
Yes, the form looks and works great in all browsers, but it doesn’t meet spec. Can any of these be cleaned up?
