I am running WordPress 4.7.5.
I have bbPress and BuddyPress plug-ins installed (and others).
When a new user registers, I receive two identical email notices indicating New User Registration. Sent at the same time, same content, but with different message IDs.
What's more, in BuddyPress Activity feed, I show two identical activity items for "XXX became a registered member"
Has anyone else run into this and found the culprit, or a solution?
