This morning it appears to be working again.
Hi there,
I have installed Moodle on AWS machine. http://nayamoodle.ddns.net
When I try to register (self authenticate) I see that the "create user" button does nothing.
Debugging the console I see:
signup.php:1 This page includes a password or credit card input in a non-secure context. A warning has been added to the URL bar. For more information, see https://goo.gl/zmWq3m.
