Was it a scheduled post?
Are you using any custom post statuses on your site?
Edit: since you have the ‘Auto Publish’ setting enabled, neither of the above 2 questions should have any effect on whether or not a post is published to Discourse. We know that the Discourse publish-post function was called, because that’s what sent the email.
It’s possible that people are unchecking the ‘publish to Discourse’ checkbox when they save a post as a draft. If that’s the case, they don’t need to do that. Drafts aren’t published to Discourse.
When you looked at the post, was there a notice saying that it had failed to publish to Discourse? Was it a scheduled post?
If you’re getting no notification for a post, then the wp-discourse publish function probably isn’t being called. The wp-discourse publish function hooks into the WordPress save_post action. I’ve seen cases where that action isn’t called when a post is published by the wp-missed-schedule plugin.
The post had not failed. It was a draft post published by another author. I’m not sure if it was scheduled or not - @beschizza, when you published the post above, did you schedule it or just publish it directly?
After you published it, was there a notification on the post edit page saying that the post had been published to Discourse, or that the post had failed to publish to Discourse?
There’s probably nothing there, but it would be great if someone could check the Discourse error log for a post that has failed to publish to Discourse and hasn’t sent an email notification.
@scossar interestingly, none of those generated an error message. They’re all from the same author but I think that’s coincidental. I’m trying to track down who posted them live to see how they were posted.
