Problem with Webmin and Apache

[dime]

I started using some dedicated server and I have Webmin as control panel. There is also Apache that I turned on and it worked.

But since I didn't find anything to access server via ftp, I searched on net and understood that I need to install some module for it on Webmin.

In list of inactive modules I found Proftpd and install it. And then I made problem: somewhere in Webmin where is administration of users I edited user "ftp" since when logging I went to directory /var/ftp and I wanted to go to /var/www/html.

But when I changed accessing directory from /var/ftp to /var/www/html it didn't work so I again moved to /var/ftp. After that I again couldn't access but noticed in file manager under Webmin that content of /var/www was moved to /var/ftp and previous content of /var/ftp disappeared. I created new directory www in /var and copied in file manager content from /var/ftp but again when access from public address I receive error 403 forbidden. I rebooted system but again same.

So could someone help me with this? I'll provide you with more informations if it is needed.
Thanks in advance
