How to enable FTP on Plesk
To enable FTP on plesk you will have to shell into the server. Once in your server you will have to run these commands.

To turn on FTP run:
chkconfig ftp_psa on

Turnning off the ftp service would be the first trouble shooting setup if the ftp service was running but not working.

To turn off FTP run:
chkconfig ftp_psa off

The FTP files for Plesk is located on the xinetd service. So make sure you have the xinetd is also turned on.

To check the status of xinetd run:
service xinetd status

To start if stop run:
service xinted start

And if you need to stop run:
service xinted stop
