(SOLVED) net2ftp no login and give me some errors

[nuno]

Try looking around the side but had no answer then I will ask here!
I login in filemanger the first time, then never :
Unable to login to FTP server localhost with username foo@foo.net.
(foo@foo.net - is my user)

Code:

The error occured in file /var/www/ispcp/gui/tools/filemanager/includes/filesystem.inc.php on line 64.

    * function ftp_openconnection (/var/www/ispcp/gui/tools/filemanager/modules/browse/browse.inc.php on line 223)
    * function net2ftp_module_printBody (/var/www/ispcp/gui/tools/filemanager/main.inc.php on line 314)
    * function net2ftp (/var/www/ispcp/gui/tools/filemanager/index.php on line 59)
          o argument 0: printBody
