Yes, I can login now and the redirect issue to localhost is solve. New problem is login page can be access if the user already login. Your auth have users roles. And I believe only user with level admin can access the backend page. And Test user only can access frontend page. Try login with admin credential. I'm on GMT 8 already 4a.m now, hope other member will helps you solve the problem. Will continue tomorrow..
KeepĀ calm.
