 * When making any setting changes or clicking the Save button on the plugin’s setting
   page, I get the following error in the browser console:
 *     ```
       admin.js?ver=2.1.2:391 Uncaught TypeError: Cannot read properties of undefined (reading 'send')
           at updateMainTriggerEle (admin.js?ver=2.1.2:391)
           at HTMLInputElement.<anonymous> (admin.js?ver=2.1.2:356)
           at HTMLInputElement.dispatch (jquery.min.js?ver=3.6.0:2)
           at HTMLInputElement.v.handle (jquery.min.js?ver=3.6.0:2)
       ```
   
 * I’ve reinstalled the plugin to make sure nothing’s missing.

 * Forgot to mention that this is a new installation of the plugin on a test site
   for a site that runs the previous version successfully. I was testing the update
   after reading about some issues with the latest release, and pow!

 * Hi Gal,
 * Sorry to hear you are experiencing issues.
 * The problem is we are using wp.ajax.send to make the ajax call
 * The wp.ajax object is defined in the wp-includes/js/wp-util.js, it is called 
   by default by WordPress
 * Wordpress Utils JS file is not loaded properly so it caused the error and you
   can check to see if that file is loaded within your admin side?

 * After not getting a reply, I decided to update the plugin on the live site and
   see what happens, and it seems OK.
 * Looking at the admin page code, the test site really isn’t loading wp-utils.js,
   while the live site does.
 * What would cause that?

 * We have the plugin “Disable Woocommerce Bloat” installed. I temporarily disabled
   this plugin and now the save feature works.

 * [@galbaras](https://wordpress.org/support/users/galbaras/) honestly, we couldn’t
   say without recreating your test environment. It could be anything.
 * [@1stwebdesigns](https://wordpress.org/support/users/1stwebdesigns/) we will 
   try to create your issue using Disable Woocommerce Bloat and look into a different
   way of saving the setting,
