 * I think the description is misleading. Javascript codes are parser blocking instead
   of “render blocking”, although in blocking parser, they may block render too.

 * You’re right, but as you write if the parsing is blocked, so is the rendering
   so in the end it’s not really wrong. And given the fact[ Google calls it “render blocking” as well in (the title of) their recommendation](https://developers.google.com/speed/docs/insights/BlockingJS),
   this is the term that is most widely known (and searched for) 😉

 * Hi Frank,
    Sorry if I’m thread jacking, for some reason I can’t seem to create
   a new topic in the support forum here. I’ve gotten the app installed and configured
   on [https://www.rsvpbayarea.com](https://www.rsvpbayarea.com), but no matter 
   what the settings, GT Metrix doesn’t seem to see that the defer parsing is working.
   I’ve tried both Async and Defer, as well as adding in a specific js mentioned
   by GT Metrix and it still appears when re-running the test. (Cloudflare is, of
   course, in development mode when I run the test)
 * Thanks!
    Eric

 * I would have to see your site with Cloudflare rocketloader disabled (and asyncjs
   enabled) to be able to comment on this [@rtmeric](https://wordpress.org/support/users/rtmeric/)

 * Thanks Frank! I just put Cloudflare into development mode so it should be displaying
   natively from my server, and asyncjs is enabled- not crucial that I turn Cloudflare
   back on today.

 * looks like something is messing with the script output [@rtmeric](https://wordpress.org/support/users/rtmeric/));
 *     ```
       <script type='text/javascript' defer='defer' src='//rsvpbayarea.com/wp-includes/js/jquery/jquery.js'></script>
       <script type='text/javascript' defer src='//rsvpbayarea.com/wp-includes/js/jquery/jquery-migrate.min.js' onload =></script>
       <script type='text/javascript' defer src='//rsvpbayarea.com/wp-content/themes/Divi/js/custom.min.js' onload =></script>
       <script type='text/javascript' defer src='//rsvpbayarea.com/wp-content/plugins/divi-builder/core/admin/js/common.js' onload =></script>
       <script type='text/javascript' defer src='//rsvpbayarea.com/wp-includes/js/wp-embed.min.js' onload =></script>
       ```
   
 * -> the first one is OK and is what asyncjs would produce, but the 4 other ones
   are not.
 * so the question now is; what is doing that? any other perf. optimization plugin
   you’re using that migth be causing this?

 * I don’t think so. I attempted a manual modification of functions.php, but it 
   seemed to not be effective, so I removed the code. Just went through and disabled,
   one by one, everything except my main theme (elegant themse/divi), backup plugin(
   updraft plus), and wordfence (security)and tested after each with the same result?

 * well, try switching to a default theme and also disable WF & updraft for a second
   next? and double-check your functions.php for remnants of the modification?
