attachments on WYIWYG

[renlok]

im trying to get a WYSIWYG editor working on my site i have everything working on the editor except when you click the attachment button (between the smilies drop down and the forwards/backwards arrows) nothing happens

ive have the code

PHP Code:

    require_once(DIR . '/includes/functions_file.php');
    $attachinfo = array(
        'auth_type'     => (empty($_SERVER['AUTH_USER']) AND empty($_SERVER['REMOTE_USER'])) ? 0 : 1,
        'userid'        => $vbulletin->userinfo['userid'],
        'max_file_size' => fetch_max_upload_size()
    );

    $editorid = construct_edit_toolbar($mod['description'], false, 2, true, true, true, 'fe', '', $attachinfo); 


so i should be able to have attachments i followed the article at https://vborg.vbsupport.ru/showthread.php?t=228693

but i dont know why the attachments dont work is it a bug or something?
