Encountered a 500 internal server error while posting, but the discussion actually went out!
It's annoying. Because of the low reach rate of the mail server, I chose to delete the email in the administration, and then it still tries to send the email????
Post some information here like what you expected to see, but got instead. If you can find any logs in /storage/logs or in your browser console that relate to the issue, add them.
