title: Facebook-like-box Safari issue: appears in some browsers, disappears in others
body: <p>I have put a facebook like box on a website i've created, and on my computer it all works fine (safari, chrome, firefox, ie, ...)</p>
  
  <p>But when some of my friends open the website in safari, de box won't show to everybody. 
  (so some friends can see it in safari, with others it just won't show/appears and disappears immediatly/...)</p>
  
  <p>Here's the iframe-code i've included</p>
  
  <pre><code>&lt;iframe src="//www.facebook.com/plugins/likebox.php?href=http%3A%2F%2Fwww.facebook.com%2Fpages%2FLuca-Barassii%2F126244157780&amp;width=300&amp;height=340&amp;colorscheme=dark&amp;show_faces=true&amp;border_color&amp;stream=false&amp;header=false" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:300px; height:340px;" allowTransparency="true"&gt;&lt;/iframe&gt;
  </code></pre>
