Hi Szymon,

I've seen these information on the facebook forum but this solution does not work and furthermore the page you give as example contains 196 errors ...

So I put the html version as specified on the Open Graph Protocol:
<html xmlns:og="http://ogp.me/ns#">

and I get the error: “Missing xmlns attribute for element html. The value should be: http://www.w3.org/1999/xhtml”
See on http://www.agencearagon.com
