I have installed the ISPConfig 18.104.22.168 beta released on Debian 5.0 VPS, everything worked fine.
I created a client -> website -> ftp-account ( worked fine)
logged to FTP with username and password and i get directory restricted ( I can't seen any file or ls or dir nothing happens )
I will post the output now
