การติดตั้ง CKeditor และ CKfinder ใน Codeigniter พอดีติดปัญหาเรื่องการเปิดหน้าต่างจัดการครับ

<?php
$session = unserialize($_COOKIE['ci_session']);
 
$user_id = $session['user_id'];
$baseUrl = '/ckfinder_userfiles/' . $user_id . '/';
?>

<script src="<?php echo base_url(); ?>js/ckeditor/ckeditor.js" type="text/javascript"></script> 
<script src="<?php echo base_url(); ?>js/ckfinder/ckfinder.js" type="text/javascript"></script>

<textarea cols="80" id="page_detail" name="page_detail" rows="10" ></textarea>
		<script type="text/javascript">
			//<![CDATA[
