Likewise I also have a similar problem. The website, specifically registration, has been working well for years. There were two recent BuddyPress updates, and at about the same time there were also two S2MemberPro updates. We use both at our website. Likewise, the new registered emails are now all of a sudden broken. The complaint I’m seeing others list is there is not any link in the email to click. The email comes with short code rather than a clickable link to verify the newly registered person’s email address. I don’t see a solution. Anyone find one?
