It seems to be an issue with cloudflare.
<script type="text/javascript">window.__CF=[];window.__CF.DJS=[];window.__CF.DJS.push({atok:'7355310e38d9715644772b5298bb1c5e',p:1305294131,byc:0});((function(a,b){var c=a.__CF,d=b.createElement("script"),e=b.getElementsByTagName("script")[0];e.parentNode.insertBefore(d,e),d.src="//ajax.cloudflare.com/cdn-cgi/nexp/v=748589472/dominate.min.js"})(window,document);</script>
I have no idea where that code came from, nor why it's on my site, but I can't remove it.
