I'm currently modify a site left from the previous developer. I'm working to modify some javascript. However, all of my changes only works in my localhost site, and not the staging site. I viewed the source code on browsers and see those script links has changed to something like this <script type="text/rocketscript" data-rocketsrc='...'></script> which I believe my updated JS codes won't work because of that.
I also see the cloudflare cdn code above it as well:
<script type="text/javascript">
//<![CDATA[
try{if (!window.CloudFlare) {var CloudFlare=[{verbose:0,p:0,byc:0,owlid:"cf",bag2:1,mirage2:0,oracle:0,paths:{cloudflare:"/cdn-cgi/nexp/dok3v=1613a3a185/"},atok:"204f23173dc3b0ee3fe57272b30ddbf2",petok:"6d99c6da0f9c5af0b780fc54f705ae1b6732742a-1439571640-1800",betok:"1b5c428c2c19f5473b41af6d945e42424041cb79-1439571640-120",zone:"hagarstage.com",rocket:"a",apps:{}}];document.write('<script type="text/javascript" src="//ajax.cloudflare.com/cdn-cgi/nexp/dok3v=e9627cd26a/cloudflare.min.js"><'+'\/script>');}}catch(e){};
//]]>
</script>
But my localhost site does not have this kind of script loading.
I explored all the plugins and there is no cloudflare related plugins installed. I believe that my codes will take effect once I have removed this script.
I see the link here https://wordpress.org/support/topic/cloudflare-code-left-after-uninstalling. However, no one answered it. So is there any way to completely remove this script?
We would only insert that JavaScript if the site was on the CloudFlare network in some way (signed up directly/through a hosting partner). It looks like Rocket Loader is turned on & turning on optional performance features (like Rocket Loader) or apps would inject JavaScript on your site that are running through the proxy (that's why you see a difference checking your server directly).
