How To Enable IP-Checking?

How does one enable IP-Checking?

You don't activate it. The administrators can see it in the ACP

But how can Mods be able to see it? Example, in the chatbox, you can right-click on somebodies name and say check IP.

I don't think you can do that in forumotion. Lets see what the FM Staff say about it

How would I access this?

You access it by clicking on the IP button in the post:

It doesn't have that button on mine.

(I am creator and head administrator of my forum, so I SHOULD see it.)

Check here for an image:
Administration Panel > Display > Colors & Pictures > Pics Management
Advanced Mode
Buttons Tab
View IP address of poster:

Check if you have the button. ACP >> Display >> Pics Management >> Advance Mode >> Buttons.
