 * Hi Frank. Know you’re testing 1.3.3, so wanted to let you know that when I run
   saf3.staging.wpengine.com through validator.w3.org, I get the following error:
 * Line 128, Column 2297: Bad value true for attribute async on element script.
   …
   te/lyte/lyte-min.js?wyl_version=1.3.3″></script><script type=’text/javascript’…
 * that first > is in red.
 * Hoping you can fix this with the update. Thanks again for the great plugin and
   wonderful support.
 * Kevin

 * Right! Fixed and checked, if you re-download the zip-file for 1.3.3 test, this
   should be gone.

 * Thanks Frank. I might be pushing my luck at this stage, but GTMetrix marks saf3.
   tv down on its PageSpeed score because:
 * Resources with a “?” in the URL are not cached by some proxy caching servers.
   Remove the query string and encode the parameters into the URL for the following
   resources:
 * [http://2nmx781wumfx1n1k62oe6lsy5h.wpengine.netdna-cdn.com/wp-content/plugins/wp-youtube-lyte/lyte/lyte-min.js?wyl_version=1.3.3](http://2nmx781wumfx1n1k62oe6lsy5h.wpengine.netdna-cdn.com/wp-content/plugins/wp-youtube-lyte/lyte/lyte-min.js?wyl_version=1.3.3)
 * So be great if you could also tweak this in the upgrade.
 * Thanks again for the amazing plugin and even more amazing support.

 * Nah; it’s to important to be able to break any caching by just changing the version
   string (while not having to change the filenames themselves).
 * But you could solve this by using a JS/CSS optimization plugin though, that could
   speed your site up substantially on top of the fixing the resources-with-querystrings-
   issuette.
 * I might know a good optimization plugin, but I’m biased 😉

 * Fair play. I’m using WPEngine, which optimises JSS and CSS already, but I’ll 
   try out AutoOptimize on the next site I build on a different host. Thanks again.

 * Well, when looking at your site, WPEngine does not seem to be aggregating & minimizing
   CSS/ JS?
 * But they sure are doing a nice job, performance-wise (they do have great page
   caching technology which is their own, so they don’t allow e.g. W3 Total Cache
   of WP Super Cache).

 * Good to know. Will try see if I can run AutoOptimize alongside it. And yes, WPEngine
   has been a dream so far. Thanks.
