WP-Admin Redirection vers le HTTPS WordPress
So if you are having this issue only when you go to ../wp-admin then it is
because you have force ssl admin set to true. You can find this in
wp-config.php in the root of your WordPress site, you need to set this option
to false.
define('FORCE_SSL_ADMIN', false);
I am assuming your siteurl in the wp_options table in the WordPressdatabase is
set to a http:// address.
