title: URL could not be liked because it's been blocked
body: <p>I am developer of <code>www.iloveskola.lv</code> and I have created facebook login with API.
  After user logs in with his facebook account he has opportunity to participate in voting game. </p>
  
  <p>One question, 4 answers.
  Each answer is facebook LIKE button. </p>
  
  <p>When user press like button, LIKE content on facebook has been created automatically.
  First 2-3 days its was working perfect, but now when user press button iframe content just blinks and nothing.</p>
  
  <p>I checked this with mozilla(bug zilla) and saw following response:</p>
  
  <pre><code>for (;;);{"__ar":1,"payload":{"success":false,"show_error":true,"error_info":{"brief":"Invalid url","full":"URL could not be liked because it's been blocked.","errorUri":"\/connect\/connect_to_node_error.php?title=Invalid+url&amp;body=URL+could+not+be+liked+because+it\u002527s+been+blocked.&amp;hash=AQAh-oNvuhmlqYzH"}}}
  </code></pre>
  
  <p>For deep investigation you can try this system by yourself.
  If our site is blocked want to hear explanation why this is happening.</p>
