Re: Another activation issue.
Oh so emails are being sent then!
As mentioned work in just WP ensure that option to allow user registration is set and test again and send to an account that you has no issues i.e accounts like hotmail can be problematical as they implement iirc SPF records and will likely reject emails coming from a domain they can’t verify so ensure the sending address is real. There are quite a few threads on the support forum on this subject that cover most of what I can suggest and more, so they are worth tracking down although I admit searching can be awkward.
