wrong og:description

Facebook does not get information from description Open Graph tags I do get following error but not for description field

The og:url property should be explicitly provided, even if a value can be inferred from other tags.

I do have in header 开发者_如何学运维(Wordpress)

<meta property="og:description" content="<?php echo strip_tags(the_excerpt()); ?>" /> 

bugzilla shows correct source of the page

<meta property="og:description" content="<p>3D organs modeled for real-time DVD application</p>" />

But on fb page description shown is JavaScript code from google analytics :)

"var _gaq = _gaq || []; _gaq.push(['_setAccount'..."

Do you spot the error somewhere?

By the way... I know fb caches information... is there a way to reset it?

To refresh the cache run the url through Facebooks URL Linter here http://developers.facebook.com/tools/debug. What is the url you are trying to parse?
