I have a site that the comment notifications do not work. However the password reset email DOES work.
A couple of things I’ve noticed.
The site is a subdomain (I have another site in a top level domain that the notifications do work.
I have tried SMTP Mailer and WP-smtp. I had trouble getting the test emails to work, but even after I did, the notification emails still do NOT work.
I have tried disabling all plugins and notification emails still do not work, either with the default configuration, or with either of the SMTP plugins.
Is there a way I can see logs of what’s going on?
