 * The plugin is working very well up to version 3.1.2. When we upgrade to a new
   release, the plugin is working for one day, after one day we get problems, no
   images or logos are loaded. If we purge the cache it is working again for one
   day.
 * Merging of css and javascript is enabled. Load jquery in footer is enabled in
   the theme settings.
 * Cache lifespan is set to 0
 * Loading failed for the <script> with source “https://xxx.xxx/wp-content/cache/
   wpo-minify/1648665558/assets/wpo-minify-footer-7c5f63f7.js”. xxx.xxx:394:1

 * @wipx `jQuery is not defined` is very generic and couldn’t guess what can be 
   issue with WPO. My guess is that either you have excluded `jQuery` from minified
   settings or other plugins/theme dequeues `jQuery`

 * Thank you, jquery is not exluded no plugins dequeues jquery.
 * This started when I upgraded from 3.1.12 to the next version. I then went back
   to 3.1.12 and have been using it until now when I tried 3.2.3. The WPO settings,
   theme and plug-ins are the same.
