Quick Edit Spinning

I had a developer who installed the ultimate plugin. They referred me to you with this problem I’m having.

-We have been able to locate the cause of the Quick Edit feature error. It is an issue within the plugin WCFM – WooCommerce Frontend Manager – Ultimate. This plugin is up-to-date, with the latest available version installed, so it is up to the plugin author to fix the mistake. You can send them the info below and ask them to look into it.

The error is in this script:
…/wp-content/plugins/wc-frontend-manager-ultimate/assets/js/wcfmu-script-core.js

Here are the error details:
