How I can allow moderator see ip?

[katana]

Hi to everyone.
After upgraded my vers. 5 with the 6 moderators are not allowed to see user's IP.
I read your manual which suggests to change "moderatorSeeIp" ON (in Default.XML) but I didn't find that row in my file.
I tried to add that line in the file but nothing changed.
How I can allow my moderator to see user's IP with the new version?
Thank you in advance to everyone can help me.

Open the default.xml file under this dir: \123FlashChatServer6\server\etc\groups

Find: <moderatorSeeIP enable="Off"></moderatorSeeIP>

And set the value as On
