The plugin seems to be functioning fine, the links all show up on the site, no errors. Problem is that no eMails are being generated to other domain addresses. I have ensured the eMail templates were set to yes.
I was using Easy WP SMTP to allow eMails from my server then switched to WP Mail SMTP but the problem persists. The eMails are being sent to me at my domain eMail but it won’t send to eMail addresses at other domains. Can you make the plugin work with either of these SMTP plugins?
