[jQuery] jQuery Ajax Bugs?

[F8R]

I have use jQuery to send AJAX call to PHP script using POST.
It's always execute error function callback.

I check using FireBug Firefox extention, the passed XMLHTTPRequest to
error function callback has some of this value :

readyState : 4
status : 200
responseText : {The expected response}
statusText : "OK"

Here some of my code :

            $.ajax({url:'inc/
msgboard.php'.url,type:'POST',dataType:'html',data:'name=F8R',
                success : function(passed) {

                    }
                },
                complete : function() {

                },
                error : function(err) {
                    alert(err ? err.responseText : 'Request GAGAL,
silakan coba lagi beberapa saat.\nContent tidak ter-Update.');
                }
            });

I'm using Windows XP and Apache 2.2 as test.
