 * It appears that there is a javascript error in console:
    `TypeError: e.ajax(...).
   done(...).complete is not a function[Learn More] smush.js:817:4`
 * Running Smush together with Hummingbird (default settings) and Woocommerce. The
   theme is Storefront by Woocommerce.

 * Using jQuery 3.3.1, without jQuery migrate. I believe the default jQuery library,
   shipepd with WordPress is 1.12.4.

 * In newer versions of jQuery the format changed a bit. So you should use either
   the default jQuery version from WordPress, or use jQuery migrate

 * ..or you can update your plugin’s JavaScript code to use the **recomended (and
   without security issues)** version of jQuery?
 * I’ll give you 1 star until then.

 * Smush has been updated to fully support the latest version of jQuery. The fix
   will be available in the upcoming update. Thank you for reporting this.
 * Best regards,
