Hello,
you’re using an older version of the plugin. Would you please update the plugin to the latest 2.7 version? On the “WP Admin -> Plugins” page there should be an update notice next to the plugin’s name.
Thanks, Diana I updated it and I still have the same issue
In your “storefront-child” theme there is a template file added that modifies the coupon form. The file’s path is /wp-content/themes/storefront-child/woocommerce/checkout/form-coupon.php.
Normally in that file the <form> element has the “checkout_coupon” CSS class. Your <form> element has this class missing, therefore the form cannot initiate the AJAX application of the coupon. Note that this issue is independent of the multi-step checkout plugin. If you deactivate the multi-step checkout plugin, then you’ll see that, when applying the coupon, the page refreshes.
If you add back the “checkout_coupon” CSS class, then the coupon can be applied to the order through AJAX, i.e. without refreshing the page. See this screenshot.
perfecto, ya quedó. gracias
