When changing template or updating template for blogspot I always encounter this on a customize template.
This warning appear under the heading ‘Extracted rich snippet data from the page’ – ‘hfeed’ and ‘hentry’ in the Google Webmaster Tools Rich Snippets Testing Tool.
This is a short description ( Google Webmaster Tools - Rich Snippets Testing tool, documentation ) about rich snippets and structured data :

The simple solution insert the vcard in post body after the post or before the post some template miss place this and the Google snippets can't read it.

I already have a scripts like this but this one is a built in my template which is not working.

FIND THIS ON YOUR HTML ( In some template you can see two of this select the upper one or test where this scripts worked)

<div style='clear: both;'/> 
</div>

or find this

<b:if cond='data:blog.pageType == "static_page"'><data:post.body/></b:if>
