The theme is not compatible with Measurement Price Calculator of WooCommerce.
In ‘etheme.js’ i found this.
var data = {
action: 'et_woocommerce_add_to_cart',
product_id: form.find('[name="add-to-cart"]').val(),
quantity: form.find('.qty').val(),
variation_id: form.find('[name="variation_id"]').val(),
variation: variation,
};
So the data of the plugin is not send to your add to cart hook.
Is it possible to fix this, without making the theme or plugin un-updateable?
