[RESOLVED] Problem in using ftp_choose_dir.php with CentOS 5.4, PHP 5.2.11

[rexsham]

I setup with a fresh CentOS 5.4 with all software packages listed in the documentation and followed the steps in the documentation.
php 5.2.11 mysql 5.1.41
Apache/2.2.3 (CentOS)
MySQL client version: 5.0.67
PHP extension: mysql
ispcp 1.0.2 stable also with ispcp 1.0.3 2009.12.17 nightly build, both with same problem

phpmyadmin , SQL and email are ok but the FTP and filemanager do not work.

I cannot get the FTP working correctly, when I access "Add FTP user"
I see the page like this:
   

I have used over a week to find the problem but i am too stupid to have that problem found.
