Users Not Receiving Activation Codes

Hey! So this plugin was working great initially, but lately my users are telling me they’re not receiving their activation codes, so I have to manually send them. The activation code is still showing up in the profile, it’s not being sent in an email. I think there’s a problem with the new version.

It’s not a huge imposition to send it manually, I get maybe 10 users a week and I don’t really mind doing it, but it’d be great if this could be looked into.
