I have Members enabled, connected to Mailgun with valid credentials. Running Ghost 3.1, self-hosted on DigitalOcean Ubuntu droplet. I am also using the Lyra theme.
If “Allow free member signup” is TRUE, the email on the Lyra signup page gets sent perfectly fine.
However, if “Allow free member signup” is FALSE, the email on that same page never gets sent. The status message beginning “Great!” shows up instantaneously.
Signup page is here: https://exceptionnotfound.net/signup. Obviously, “Allow free member signup” is currently TRUE on that page.
