Issue with Facebook Activity Feed plugin on my website

I have used face book recent activity script in my website,But it does not show anything in side the box where the script is placed,even I have feeds from my friend list.

Here is the code what I have used :

<iframe src="http://www.facebook.com/plugins/activity.php?site=http%3开发者_如何学GoA%2F%2Fintegration.mytaste.com.au%2F&amp;width=300&amp;height=300&amp;header=true&amp;colorscheme=light&amp;font&amp;border_color&amp;recommendations=false" 
    scrolling="no" 
    frameborder="0" 
    style="border:none; overflow:hidden; width:300px; height:300px;" 
    allowTransparency="true">
</iframe>

you can just test it from here itself

http://developers.facebook.com/docs/reference/plugins/activity/

use this url http://integration.mytaste.com.au/ for domain field in the box.

It doesn't look like you have any Open Graph tags on any of the pages on your site. Check out the Open Graph Protocol documentation and add at least the og:title, og:type, og:url, and og:image meta tags to your pages to have them start showing up in the Activity Feed plugin. You can use the URL Linter to ensure your pages are getting scraped correctly by us.

P.S. The auto-posting to a user's wall when they click your Like button is sort of misleading and could be called out as such by our Policy team (check out the policies). I would suggest you just use the Like Button instead. It has the added benefit of giving social context even if the user isn't logged in to your site. If you need to detect when a user has liked something on your site, you can subscribe to the "edge.create" event using FB.Event.subscribe in the Javascript SDK.
