I'm not sure how to debug this particular issue at present.
If you view this category page for example and hit the 'Buy' button on the top product, a popup will appear, hit the 'Proceed to Checkout' button and a Fancybox modal appears briefly displaying a 404 error - would someone kindly use their browser dev tools and point out why it is loading the 404 error page within the Fancybox modal please?
The script that is controlling this has become a bit of a mess but I have provided it below for reference...
<script type="text/javascript">
jQuery.noConflict();
jQuery(document).ready(function(){
jQuery('.fancybox').fancybox(
{
hideOnContentClick : true,
width: 382,
autoDimensions: true,
type : 'iframe',
showTitle: false,
scrolling: 'no',
onComplete: function(){
jQuery('#fancybox-frame').load(function() { // wait for frame to load and then gets it's height
jQuery('.fancybox').height(jQuery(this).contents().find('body').height()+30);
jQuery.fancybox.resize();
});
}
}
);
});
function showOptions(id){
jQuery('#fancybox'+id).trigger('click'); //show the custom options on click if they exist
}
function setAjaxData(data,iframe){
if(data.status == 'ERROR'){
alert(data.message); //show error message if nothing to update
}else{
if(jQuery('.block-cart')){
jQuery('.block-cart').replaceWith(data.sidebar); //otherwise update the cart in the sidebar block
}
if(jQuery('.header .links')){
jQuery('.header .links').replaceWith(data.toplink); //otherwise update the cart in the header block
}
jQuery.fancybox.close();
}
}
function setLocationAjax(url,id){
url += 'isAjax/1';
url = url.replace("checkout/cart","ajax/index");
jQuery('#ajax_loader'+id).show();
try {
jQuery.ajax( {
url : url,
dataType : 'json',
success : function(data) {
jQuery('#ajax_loader'+id).hide(); //if success, hide #ajax_loader
jQuery('.popup-text').html(data.message); //if success, show .popup-text that says product is added to cart
jQuery('.fancy-popupbox').show(); //if success, show .fancy-popupbox content
//jQuery.fancybox.open('.fancy-popupbox');
setAjaxData(data,false);
}
});
} catch (e) {
}
}
</script>
Please let me know if I can supply some further information on this.
