We had the registration all set up to send out an email. As we added, and tested, each plugin, we would test the registration process. We backed up after every change we made. After the last change, where we were trying to change profile fields, we noticed the emails no longer were being received after registration. We went back to the prior backup. Same results. We went back to the backup before that. Same results. We are contacting WP, BP, WPMU DEV and our hosting site in the hopes that someone can answer us. Why aren’t the emails working, even after going to an earlier backup when we knew it was working? Please help! We are at a complete loss!
