Hi @webslzm,

I hope you are well today and thank you for your question.

The theme is compatible with ajax.

Do the plugins work fine with any default WordPress theme such as Twenty Nineteen?

Please also contact the plugin support to resolve the issue.

Best regards,
Shufflehound team

obviously you should you a completed order in your account to simulate this issue.

Do I need to purchase something on your website by placing an order to simulate the issue?

As described above, have you tested it clearing and temporarily deactivating the SG optimizer cache and using the Jevelin theme instead of the child theme that you are using on your website?
<div class=”bbp-meta”></div>

This second video is related to ajax and minimum-max quantity:

The button ‘Update Cart’ doesn’t work properly and ajax doesn’t work absolutely

I can see the error “Your cart cannot contain more than 10 products.” in your shared video that is related to WooCommerce plugin configuration.

This is the video related to invoice download issue:

obviously you should you a completed order in your account to simulate this issue.

You can resolve it by adding the following CSS code in the Custom CSS code option of your theme on the below path.

Admin Area -> Appearance -> Theme Settings -> Custom Code -> CSS Code

body.woocommerce .sh-page-loader,
body.woocommerce-page .sh-page-loader {
    display: none !important;
}

Ya you can see the error, but only if you click on ‘Continue’. If you click on update it doesn’t work. Also Ajax doesn’t work, so the error is shown only when you go to purchase and not authomatically. please look here: thetimebox.gift —> this is how the configuration works with a working theme (Native).

It seems the issue of AJAX plugin that conflicts with some themes as described on the below pages so please contact the plugin support to get more information about it as we can’t do anything in this case because we are not aware of the plugin code.

Yes, as said this a conflict issue of the AJAX plugin that you are using and the theme but we don’t know exactly why this is happening and couldn’t troubleshoot it as we are not familiar with the plugin code.

Still, we troubleshoot the code of woocommerce-ajax-cart plugin and found out the below code added in the plugin /woocommerce-ajax-cart/assets/wooajaxcart.js is not getting executed even though the theme displays its wac-btn-inc selector in the markup.

        if ( $('.wac-btn-inc').length ) {
            $('.wac-btn-inc').off('click.wac2910').on('click.wac2910', fnIncrement);
            $('.wac-btn-sub').off('click.wac2911').on('click.wac2911', fnDecrement);

            if ( $('.grid').length ) {
                setTimeout(wacListenQtyButtons, 500);
            }

            // fix common style problem in single product page
            $("<style type='text/css'>.product .quantity { display: inline; float: none !important; margin-right: 0 !important; }</style>").appendTo('head');
        }
        else {
            $(document.body).off('click.wac3000').on('click.wac3000', '.wac-btn-inc', fnIncrement);
            $(document.body).off('click.wac3001').on('click.wac3001', '.wac-btn-sub', fnDecrement);
        }

I request you to please contact woocommerce-ajax-cart plugin support and tell them the above thing along with sharing your website URL.
