Answer 1

Your ajax add to cart JS overriding default productAddToCartForm.submit function.

You can find this unction end of the JS file

jQuery(document).ready(function($) {
    SnsProaddto.init();
    setInterval("SnsProaddto.init()", 1000);
    window.setLocation = function(args) {
        if (args.indexOf('checkout/cart/add') !== -1) {
            SnsProaddto.locationAddtocart(args);
        } else if (args.indexOf('?options=cart')) {
            SnsProaddto.destroyImgFly();
            window.location = args;
            //SnsProaddto.displayOptions();
        }
    }
    if (typeof productAddToCartForm != 'undefined') {
        productAddToCartForm.submit = function() {
            if (this.validator.validate()) {
                SnsProaddto.destroyImgFly();
                jQuery('#proaddto_loading').show();
                var dataf = jQuery('#product_addtocart_form').serialize();
                dataf += '&isAjax=1';
                url = jQuery('#product_addtocart_form').attr('action');
                url = url.replace("checkout/cart", "proaddto/index");
                url = SnsProaddto.cleanUrl(url);
                jQuery.ajax({
                    url: url,
                    dataType: 'json',
                    type: 'post',
                    data: dataf,
                    success: function(data) {
                        jQuery('#proaddto_loading').hide();
                        SnsProaddto.setCartResult(data);
                        SnsProaddto.flyImgToCart();
                    }
                });
            }

            else {
                // popup condition
            }
        }
    }
});
