syntax error when I click "Browse Server" button

Hi,
When I used the image tab to upload my image file, then click "Browse Server" button in Image properties, but system error as shown as attachment file. Can you help to check where should I modify?
My ckeditor\config.php contents are:
CKEDITOR.editorConfig = function( config )
{
config.filebrowserBrowseUrl = 'ckfinder/ckfinder.html';
config.filebrowserImageBrowseUrl = 'ckfinder/ckfinder.html?Type=Images';
config.filebrowserFlashBrowseUrl = 'ckfinder/ckfinder.html?Type=Flash';
config.filebrowserUploadUrl = 'ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Files'; //可上傳一般檔案
config.filebrowserImageUploadUrl = 'ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Images';//可上傳圖檔
config.filebrowserFlashUploadUrl = 'ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Flash';//可上傳Flash檔案
};

My php sample page:
<?php
include_once 'ckeditor/ckeditor.php';
include_once 'ckfinder/ckfinder.php';
$ckeditor = new CKEditor();
$ckeditor->basePath = '/ckeditor/';
CKFinder::SetupCKEditor($ckeditor, '/ckfinder/');
$ckeditor->editor('CKEditor1');
?>

My ckfinder\config.php setting:
function CheckAuthentication()
{
return true;
$config['LicenseName'] = '';
$config['LicenseKey'] = '';
//$baseUrl = '/userfiles/';-->even I changed to 'userfiles' but it still error
$baseUrl = 'http://localhost:8080/upload/';the upload folder is on "C:\xampp\htdocs\upload"
$baseDir = resolveUrl($baseUrl);
