Not able to moderate Facebook comments on my website

I've put the code for Facebook comments on my website: www.weloveisrael.org (down at the bottom). I can't seem to be able to moderate them, this is the code, what am I missing? :

<div id="fb-root"></div>
<meta property="fb:admins" content="518305576" />
<meta property="fb:app_id" content="{224255590957777}"/>
<script src="http://connect.facebook.net/en_US/all.js#admins=518305576&amp;xfbml=1"></script>
<fb:comments href="http://www.weloveisrael.org"  reverse="0" num_posts="10" width="开发者_开发百科960"></fb:comments>

You added the comments box code correctly:

<div id="fb-root"></div>
<script>(function(d){
  var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
  js = d.createElement('script'); js.id = id; js.async = true;
  js.src = "//connect.facebook.net/en_US/all.js#xfbml=1";
  d.getElementsByTagName('head')[0].appendChild(js);
}(document));</script>
<fb:comments href="example.com" num_posts="2" width="500"></fb:comments>

Then, between the HTML tags in your file (near the top), add the following:

<meta property="fb:admins" content="518305576" />
<meta property="fb:app_id" content="224255590957777"/>

You can check that you've done this correctly by entering your web page in the Debugger: https://developers.facebook.com/tools/debug
