Filemanager not working properly

[wilxp]

Hi, i got a weird problem when installing nightly built 27 Dec 08 in my ubuntu machine. If i login to the filemanager at the server machine, i can enter into the ftp directory. But if i login in another computer within the same network, i got the internal server error 500. I tried to login using other ftp client and it went fine. I tried to use the online net2ftp to login and it went fine too.

How do i resolve this inability to login remotely using the inbuilt filemanager?
