 * We have had to disable the plugin as it’s searching for old versions of jQuery
   and giving a 500 error. This in turn breaks the whole page.
    WordPress 5.5.1 
   Version 5.1.0
 * POST /wp-admin/admin-ajax.php 500
    Which is using jquery.gridrotator.min.js

 * Hi BigEd,
    we would need some more details because we are unable to reproduce
   the error. It might be useful to know what browser you use and what theme you
   have installed.
 * Thanks

 * We are using the hello Elemtor theme with Elementor.
    Although its giving a 500
   error on UI pages and parts of the site that are not using Elementor.

 * Hi BigEd,
    could you send me the text you see in the “Diagnostic” tab so I try
   to understand something more.
 * Thank you

 * Ok sure, I have enabed the plugin again to give you some output, interestingly
   and we do not seem to be getting the 500 error now so maybe it’s a side effect
   of something else. I need to monitor this a bit more to find out what has changed
   and why it was affecting the plugin.
 * We still had blank images, I set autoptimse to use no JS compression but the 
   image turning off lazy load images seemed to resolve this.
 * So this is working for now, I will come back and update this later.
 * Many thanks.
