IP Address Questions

[turkey3]

So far I am in love with Vesta! But I have a few questions/problems with IP addresses.

1) Under the IP tab in the "interface" box, what's the difference in wlan0 and eth0?
2) My IP works perfectly fine and is not shared. I want it to be shared so all users can use the IP address of my server. However, when I click "share" and hit "save". at the top it says in red: " Error: ip 192.168.1.6 is used ". It also does not let me delete that IP either. When I try to delete it says, " Error: $U_WEB_DOMAINS is not empty = 1 ".
3) Is there a way I can simply give that IP address to every single website rather than having the users select the IP address manually from the drop-down menu once it's shared? I would rather they don't see the IP address but simply make their site and enjoy it.

" Error: ip 192.168.1.6 is used ". It also does not let me delete that IP either. When I try to delete it says, " Error: $U_WEB_DOMAINS is not empty = 1 ".

1. Try to delete default.domain and all domains on your server
2. Try again to change 192.168.1.6

Error: $U_WEB_DOMAINS is not empty = -1

i didn't have any domain @ that ip, even so i can't delete him.

any help?
