title: There was an error fetching the like box for the specified page
body: <p>In the past i've succesfuly installed some like boxes, and they are still running right now.
  Recently i tried to ad the like box for an other site with the same code and i can't get i to work. </p>
  
  <p>On the like box generator page on facebook will appear the following warning: <blockquote>"There was an error fetching the like box for the specified page."</blockquote> </p>
  
  <p>I'm not that familiar with facebook but i'm amazed that sometimes it will work and sometimes i'll get this warning.</p>
