Could not retrieve data from URL from facebook with like button

I was using like button in my website with properly configured app. But right after I copied this code for Google Analytics:

<script>
  (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
  (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
  m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
  })(window,document,'script','//www.google-analytics.com/analytics.js','ga');

  ga('create', 'UA-40129864-4', 'klejner.pl');
  ga('send', 'pageview');

</script>

Facebook started to having problems with retriving data from my website (like thumbnails). After linking my site inside facebook wall I can see only url, nothing more.

Here is info from Open Graph Object Debugger which shows me that facebook is scraping my website but has problem with collectiong data: https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fklejner.pl%2Fobrazek%2FdUFNwX%2Fwiezyczka-v20

I have already tried to solve this problem with:

adding information about platfrom (website) in my app settings
adding my site URL to Valid OAuth redirect URIs (in Advanced tab)
deleting old and creating new app
deleting Google Analitycs code

No success yet.

Solution

Ok, solved. It was not the Google Analytics code. The problem was with encoding. In mysteroius way my Notepad++ changed previous used UTF-8 encoding without BOM into normal UTF-8. When i changed it back, my script started to work.

And thanks Control Alt Design, i have to change that.
