I just noticed this error message on my login page: All outgoing email is disabled because no SMTP server has been configured. No emails of any kind can be sent. When i check Admin>Email Settings, I see this: [image] I can’t post attachments, but I can upload the app.yml file if that helps. I a…

I am on the latest version. Is there any place to report it? Any additional info/files/logs needed?
