WordPress dFactory Cookie Notice Plugin

I was able to find a solution after trying multiple things. I just had to put the javascript code from google analytics between a php if condition like this:

<?php if (cn_cookies_accepted()) { ?>
<script type="text/javascript">
 (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','https://www.google-analytics.com/analytics.js','ga');
  ga('create', 'UA-#', 'auto');
  ga('set', 'forceSSL', true);
  ga('set', 'anonymizeIp', true);
  ga('send', 'pageview');
</script>
<?php } ?>
