XF 1.2 IPs not showing on "Who is Online" list

All of a sudden when I view the who is online list, no ips show up. I'm a super admin on my forum and it worked a few hours ago and now it doesn't. I checked the permissions and Admins and Mods have permissions to view ip address. Any idea why this is? The only change I made between the time it worked to when it stopped worked was editing permissions of registered users permission to delete posts.

Any help would be most appreciated. Thank you.
