Hi, I’ve got the same isssue. In “General Settings” I have e-mail verification option on, but after user registration there’s no e-mail with verification code. Moreover, the alert after registration says only: “Thank you for registration” with no information about verification email. Strange thing is, that when i manually resend the verification email from “Unverified Users” page it comes to the mailbox immediately. I checked it on two different WordPress 4.0 installations, two different servers, and I’m pretty sure, that the rest of configuration is set properly. Can anyone help?
