 * I was made aware that the mobile version of my website no longer works.
 * The slider is no longer displayed and the menu no longer works. The problem is
   in the Autoptimizion file according to Error but I can’t fix it 🙁
    Does anyone
   have a tip how I can fix it?
 * I appreciate any helpful answer.

 * First and foremost try to identify what is breaking things by just disabling 
   CSS or JS or HTML or Image optimization (incl. lazyload). Based on that we can
   see what the next steps need to be 🙂

 * It’s a Js problem. Do you know how I can fix this or should I just leave it disabled?
 * Thanks for helping!

 * OK, now in JS optimization, can you try adding one of below each line to the 
   comma-separated exclusion field and report back which one makes/ breaks the mobile
   version?
 * * `wp-content/themes`
    * OR `wp-content/plugins` * OR `wp-includes/js`

 * The Problem was the Async JavaScript Plugin
 * Thanks for your help!

 * The good news: the same exclusion logic trial&error applies to asynsJS 🙂
