Notifications not sent

Well, what changed between then and now? Here is a checklist to inspire your debugging efforts:

1. If you have replaced WP Cron with a real cron job, verify that it’s still working correctly.
2. See if Mailgun made any changes to their API or service in general that might affect your email sending.
3. Test if it works when you email via a different service/SMTP (other than Mailgun).
4. Is your email log enabled on Mailgun or are you using a WP plugin for that? If the former, try the latter to see if your WP install attempts to send emails at all.
5. Disable all non-essential plugins and see if it works then.

I can’t see that anything that affects that has changed, that’s the problem. After that I’ve updated a few plugins, but between the subscriptions working and stopping to work nothing changed (just because I wanted it to continue to work ?? )

1. No, using regular wp cron, no extra plugin or service
2. Where can I find that? All other emails are sent just fine, so would that really affect just these emails?
3. Haven’t tried that because of 5 below
4. I’m using the Email log plugin, all other e-mails are sent without any problems.
5. It works when I’m testing (my user is subscribed to the forum, I log in as another admin user and post), but two days ago one of my customers posted in the forum and I didn’t receive any notifications. I got the notification for new topic created, but not for a posted follow up reply (i.e. a new reply in the same post). If I’m subscribed to a whole forum I shouldn’t need to subscribe to each single topic in order to get the reply notifications, should I?

?? Never mind the debugging then, we appear to have found the problem.

bbPress has a different logic for what it means to be subscribed to a forum or topic. Subscribing to a forum means you will receive notifications for new topics in that forum. In order to receive reply notifications, you have to subscribe to each topic individually.

Whether you should or should not need to do this is a matter of taste. After all, you might be interested in knowing about the existence of new topics, but not care for every new topic posted.

Ok, that’s slightly annoying ??

But, my course participant created a new topic and I didn’t get that notification, however I can’t seem to recreate that problem. Are the subscriptions handled differently if an admin or a regular user creates it?

Well, if it were the other way around, people would be annoyed that they’d have to manually unsubscribe from topics. ?? But if you like it better that way, you could write a plugin to change the default behavior (or maybe someone has already created such a plugin, I don’t know).

As for the missed topic notification, the subscriptions do not differentiate between user roles, but maybe there was some other issue. Does that email show up in the email log? Then maybe it got caught in a spam filter? If it doesn’t show up in the log, would it be possible that you were not subscribed to that forum at that time for some reason? Mailgun connection error? WP Cron issue? Could be anything, really.

Even if you can’t seem to recreate the issue, I’d keep an eye on subscription emails for a couple of days just to make sure everything is working as intended.

o,. thanks. No, it doesn’t show up in the email log, that’s how I know it hasn’t been sent, but all the other emails (order notifications, scheduled follow up emails etc have been sent).
