I think ragezone need https enforce in htaccess. I always redirected to http then my session is gone. But when I manually add https on url the session is restored.
I think need this in .htaccess
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
I solve now. I just cleared the cookies for https. I just login now with http protocol without redirecting to https. I use cookie editor plugin in chrome.
