"Oops" error when clicking email link to authorize email address change

[gerhard (Gerhard Schlager)]

Confirmation email link (after change) is broken ("Oops!") due to bad email customization

You probably customized that email before we changed the link. Please go to /admin/customize/email_templates/user_notifications.confirm_new_email and make sure that link in there looks like %{base_url}/u/confirm-new-email/%{email_token} instead of %{base_url}/u/authorize-email/%{email_token} It might be a good idea to add a migration after all. This came up multiple times already. cc @sam
