Issue Error: proftpd-config failed: chown: invalid user: `root:root'

[Winnstorm]

Hello,

I'm receiving this error from the plesk admin panel today. I really don't know what happens but the server appears to be working ok.

How can I fix this error? Any clues?

Thank you
Best regards

Try to check proftpd config with

# proftpd -t

Also

# plesk repair ftp

may be useful.
