Whenever I am trying access Browse Server, page content is not load. I mean to say there show blank page.

Template Code :

    <script type="text/javascript">             
                        CKEDITOR.replace( 'editor<?=$langId[$j-1]?>',{                    
                        filebrowserBrowseUrl :'<?php echo base_url(); ?>editor/ckfinder/ckfinder.html',                    
                        filebrowserImageBrowseUrl : '<?php echo base_url(); ?>editor/ckfinder/ckfinder.html?Type=Images',                    
                        filebrowserFlashBrowseUrl :'<?php echo base_url(); ?>editor/ckfinder/ckfinder.html?Type=Flash',                 
                        filebrowserUploadUrl  :'<?php echo base_url(); ?>editor/ckeditor/filemanager/connectors/php/upload.php?Type=File',
                        filebrowserImageUploadUrl : '<?php echo base_url(); ?>editor/ckeditor/filemanager/connectors/php/upload.php?Type=Image',
                        filebrowserFlashUploadUrl : '<?php echo base_url(); ?>editor/ckeditor/filemanager/connectors/php/upload.php?Type=Flash'});          
</script>

editor/ckeditor/config.js

CKEDITOR.editorConfig = function( config )
{
    config.filebrowserBrowseUrl = 'editor/ckfinder/ckfinder.html';
    config.filebrowserImageBrowseUrl = 'editor/ckfinder/ckfinder.html?Type=Images';
    config.filebrowserFlashBrowseUrl = 'editor/ckfinder/ckfinder.html?Type=Flash';
    config.filebrowserUploadUrl = 'editor/ckfinder/core/connector/php/connector.php?command=QuickUpload&type;=Files';
    config.filebrowserImageUploadUrl = 'editor/ckfinder/core/connector/php/connector.php?command=QuickUpload&type;=Images';
    config.filebrowserFlashUploadUrl = 'editor/ckfinder/core/connector/php/connector.php?command=QuickUpload&type;=Flash';
