sabrina.zeidan on "[Plugin: Wordfence Security] Users IP's are not detected"

Hello
After server was changed the IP's stop being detected. It displays just server self IP instead of real users IP's. I found this article, but can't follow advice about Apache listen directive as I have no access to server config, my server uses IPv4. I like how Worfence works and what to use it again. Please, help
