CI 2.0 internationalization of site_url() problem

[eluser]Juris Malinens[/eluser]
Hi! I am using
http://maestric.com/doc/php/codeigniter_i18n

but it not worked by default and I modified it so now /en/test1 and /ru/test1 correctly shows English and Russian language but this code:

Code:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

// CodeIgniter i18n library by Jérôme Jaglale
// http://maestric.com/en/doc/php/codeigniter_i18n
// version 6 - April 20, 2009

class MY_Config extends CI_Config {

    function site_url($uri = '')
    {    
        if (is_array($uri))
        {
            $uri = implode('/', $uri);
        }
        
        if (function_exists('get_instance'))        
        {
            $CI =& get_instance();
            $uri = $CI->lang->localized($uri);            
        }

        return parent::site_url($uri);
    }
        
}
// END MY_Config Class

/* End of file MY_Config.php */
/* Location: ./system/application/libraries/MY_Config.php */

Doesn't override site_url() function and when I use

<p>&lt;?=anchor('music','Shania Twain')?&gt;</p>

I get /music not /en/music or /ru/music

MY_Lang.php:
