I'm having a problem with comment email notifications. I've checked the "Email me whenever someone posts a comment" setting, but I don't receive these emails.
After Googling I found other people with the same problem, but it invariably turned out to be a more general email problem.
I've installed the WP Mail SMTP plugin, and when I use it to send a test email, I receive it. I've also tried changing the email address under the admin profile and also under Settings -> General. I do get notifications when users register, and I got notifications when comments were held for moderation until I turned moderation off.
Anyone have ideas?
