Trying to get this plugin working on a site which is using Better WP Security to 'hide' the backend - basically it creates rewrite rules that add a secret key to make wp-login.php accessible.
In other words, hitting /wp-login.php returns an error, while /wp-login.php?secretkeyhere (or an alias - /log-in) allows a user to log in.
When using wp_login_url() or wp_loginout(), the modal login returns the message "Error: All fields are required."
I've tried building the key into the login in a number of ways - and would obviously prefer to not edit the plugin itself - but am having no luck. Ideally this same key could be added for registration.
Any ideas or suggestions would be greatly appreciated.
