Google Universal Analytics tracking code generating an empty page

Question

It is the first time i am using the new version of Google Analytics (Universal Analytics), so when i put the below code imediatally before </head> i get blank pages for all my URLs.

Here is the code given by Google:

<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-1234567-89', 'mysite.com');
  ga('send', 'pageview');

</script>

Someone knows why it is happening? Seems to be a bug, but i don't know how to solve this.

Answer 1

Based on @Brad comment i detected that PHP Smarty was crashing with Universal Analytics code tracking, so i found this post:

Use {Literal} Smarty Tag to Add Google Analytics Tracking Code to BlogSome Hosted Blogs

And then i did like below and the tracking code works perfectly!

<script>

    {literal}

    (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-1234567-89', 'mysite.com');
    ga('send', 'pageview');

    {/literal}

</script>
