I am having trouble getting the comments to save. They always say "Your comment could not be posted, we're very sorry for the inconvenience".

I used the developer tools in IE to trace the javascript code and I found the following error: "Extension not found or permission denied". This occurs in the following block of code on the blog post page, specifically in the if(data == 0){ part. The error seems to be on the data object. Anyone have any ideas what might be wrong?

    jQuery(document).ready(function(){
          
          
          jQuery("#commentform #email").blur(function(){
                var email = jQuery("#commentform #email").val();
                                
                if(email != ""){
                    var url = "/base/Blog4Umbraco/GetGravatarImage/" + email + "/80.aspx";
                    jQuery.get(url, function(data){
                        if(data != ""){
                             jQuery("#gravatar").css( "background-image","url(" + data + ")" ).show();
                        }else{
                            jQuery("#gravatar").hide();
                        }
                    });
                }
          });
            
          jQuery("form").validate({
              submitHandler: function(form) {
                jQuery("#commentform").hide();
                jQuery("#commentLoading").show();
                jQuery("#commentform #submit").attr("enabled", false);
                
                var url = "/base/Blog4Umbraco/CreateComment/2738.aspx";
                
                jQuery.post(url, { author: jQuery("#commentform #author").val(), email: jQuery("#commentform #email").val(), url: jQuery("#commentform #url").val(), comment: jQuery("#commentform #comment").val() },
                   function(data){
                   
                   jQuery("#commentLoading").hide();
                   jQuery("#commentPosted").show().removeClass("error");
                   
                    if(data == 0){
                          jQuery("#commentPosted").addClass("error").html(" Your comment could not be posted, we're very sorry for the inconvenience ");
                          jQuery("#commentform").show();
                          jQuery("#commentform #submit").attr("enabled", true);
                    }
                    
                   });
            }
            });
    });
