I have a new blog http://www.thewellnessdirector.com which is based on the Ten Twenty 1.2 theme, and fails the Google Rich Snippets testing tool on only one point - which is:
Warning: Missing required field "updated".
this occurs only on two posts out of about 5 or 6. (real new!).
any suggestions on fixing this - both posts are in the main part of the page.
