Hi,

Quick solution for this case is: please go to file skin/frontend/default/sns_lunar/sns/ajaxcart/js/sns-ajaxcart.js find and replace the bellow code:

function callAjax(url, action){
	if(action=="url"){

by:

function callAjax(url, action){
	if(action=="url"){
		if ( url.search('checkout/cart/delete') != -1 ) {
			window.location.href = url; return;
		}

Thanks!
