Hi, I’m having the activation email issue as well. I’m running exactly the same install as I was on a another site 2 weeks ago (before upgrading to WP 4.72) that worked fine. This one I can’t even send messages manually. I’m a plug and play person; no coding skills. If these things don’t work, I don’t know where to begin. Guidance is appreciated.
WP 4.72
WP default 2017 theme
all plugins disabled except BP
