ckeditor and ckfinder Folder not found error

Hi i have problem with ckeditor and ckfinder configuration, when i am trying to upload image i get error:
It was not possible to complete the request due to file system permission restrictions.
And When i am trying to browse server for images i get error:
Folder not found. Please refresh and try again.

My site stucture:
http://www.example.com/admin/ckeditor/
http://www.example.com/admin/ckfinder/

PHP code:

include_once 'ckeditor/ckeditor.php';
include_once 'ckfinder/ckfinder.php';
   
$ckeditor = new CKEditor();
   
$ckeditor->config['filebrowserBrowseUrl'] = '/admin/ckfinder/ckfinder.html';
$ckeditor->config['filebrowserImageBrowseUrl'] = '/admin/ckfinder/ckfinder.html?type=Images';
$ckeditor->config['filebrowserFlashBrowseUrl'] = '/admin/ckfinder/ckfinder.html?type=Flash';
$ckeditor->config['filebrowserUploadUrl'] = '/admin/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Files';
$ckeditor->config['filebrowserImageUploadUrl'] = '/admin/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Images';
$ckeditor->config['filebrowserFlashUploadUrl'] = '/admin/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Flash';
$ckeditor->editor('text');

ckfinder config.php
function CheckAuthentication() returns true
$baseUrl = '/ckfinder/userfiles/'; (default) writeable 777
$baseDir = resolveUrl($baseUrl); (default)

So where could be problem?
