 * Hello,
    I have installed this plugin to elegant theme Divi layout. I have minified
   JS and CSS, but the problem is that the google page speed insight tells me to
   optimize following file which is each time generated with different link, its
   path is: wp-content/cache/minify/000000/d5ed2/default.include.88a0fb.css how 
   i optimize this css file delivery? Also im having one more error in plugin page:
   The following minifiers cannot be found or are no longer working: YUI Compressor(
   CSS): JAVA executable path was not found. The default CSS minifier will be used
   instead. This message will automatically disappear once the issue is resolved.
 * What path i should indicate in executable and jar java files?
    Thank you in advance

 * 1. You can’t optimize it unless you load it in the footer of the website before
   the closing body tag.
 * 2. You need to add the file to your server manually and make sure that your server
   can run .jar files.
