Well, go to your vBulletin-Options in your Admin-CP. Are your IP-logging-options looking and set like this?

If yes, then click on Save changes, even if you didn't change any of the settings there.

Try creating a post with a test account (normal registered user). And look at his post, being logged in as your test account.

Try reverting the templates postbit_ip_show and postbit_ip_hidden in your Postbit Templates.

Revert all changes files and try to reapply all the changes. Maybe you just forgot something or you've made a mistake?

I have done this but nothing...

Sorry, but I need a little more Info: What do you mean with nothing and what have you done?

When I look on postbit it only shows IP: and nothing and I did everything...

mmh ... try checking the HTML-Source and maybe some other/older posts. And check, if you've updated the setting in your Admin-CP.

The thing is that when I try to view the source the freaking notepad window doesn't open, And I did update em.

I there a way so only the poster , admins and super admin can see the IP ?
I do not want the moderators to see any IP :(

Well, you could simply turn off 'Can View IPs' for every moderator in your Admin-CP

i've got this all working, but how do i make it so that the IP "seems" public only to Mods/Admins.. i checked the correct radio button.

is there a way to show the IPs of others to mods/admins WITHOUT clicking on the link to resolve the IP?

The hack is designed to work only, if you check the last option.

If you want to hide the IP from your users, just remove from the hack.
