After turning off virtualmin dav plugin I press the configuration button and get:

Using network interface eth0 for virtual IPs.

Both user and group quotas are enabled for home and email directories.

All seenms fine, I scroll down and find that proftpd has a big red x next to it, I press the buton to start it up and get this error:;

Failed to start service :

/etc/init.d/proftpd: line 19: /etc/rc.d/init.d/functions: No such file or directory

Anyclues how to fix it? It used to work, it never turned on when the server restarted but it always turned on when the button was pressed.

Closed (fixed)
