Proftpd not working after upgrade from plesk8

[Marco AugustoL]

After upgrade from plesk8 proftpd disappeared from server:

Components Manager gives me that ftp is installed:

psa-proftpd 1.3.1-cos5.build92091016.19

but ftp server is not started and when i try to start with /usr/sbin/proftpd it responds:

- warning: unable to determine IP address of '**************'
- error: no valid servers configured
- Fatal: error processing configuration file '/etc/proftpd.conf'

I resolved:

in /etc/hosts i added this line:

127.0.0.1 <whatever hostname returned goes here>

where <whatever hostname returned goes here> is the result of hostname command.

I don't know why is necessary in this server and not in another server with plesk 9.2.3.
