Great plugin, perfect for my needs!
How do I remove the warning:
Because your site is behind a loadbalancer and is_ssl() returns false, you should add the following line of code to your wp-config.php. Your wp-config.php could not be written automatically.
if (isset($_SERVER["HTTP_X_FORWARDED_PROTO"] ) && "https" == $_SERVER["HTTP_X_FORWARDED_PROTO"] ) {
$_SERVER["HTTPS"] = "on";
}
I've already added this to my wp-config and the site is functioning fine.
