title: Facebook recommendation box in iframe: url is not valid
body: <p>I am creating Facebook recommendation box <a href="https://developers.facebook.com/docs/reference/plugins/recommendations/" rel="nofollow">here</a>.<br>
  The domain is "http://www.mydomain.co.il/". For example("http://www.sport5.co.il/")<br>
  I can see the proper box to my right, but when I click "Get Code" and choose "IFRAME" I get this message: "A valid url is required when using the iframe implementation."<br>
  You can also try it.<br>
  What is wrong here?</p>
