 * Hello everyone, I am using the latest version of both plugins. They both work
   and my codes are getting highlighted (only tested shell scripts). But when I 
   inspect my website I am getting these errors:
 *     ```
       EnlighterJS.min.js:2 Uncaught ReferenceError: Class is not defined
           at EnlighterJS.min.js:2
           at EnlighterJS.min.js:3
       www.domain.com/:390 Enlighter Error: MooTools Framework not loaded yet!
       a @ (index):390
       ```
   
 * I am using js and css manual minify (Embed type: “Non-blocking using ‘defer'”),
   I’ve entered:
    `wp-content/plugins/enlighter/resources/mootools-core-yc.js` `
   wp-content/plugins/enlighter/resources/EnlighterJS.Startup.js` and `wp-content/
   plugins/enlighter/resources/EnlighterJS.min.css`
 * If anyone has an advice, please share.
    Thanks in advance for the help.

 * hi mmdollar,
 * please do not alter the js/css resources. they are already minified/optimized.
   in case another plugin modifies these file they may not work.
 * the above error message is an indicator that something went wrong with the mootools
   javascript file (it is missing). please check this 🙂
 * br, Andi
