I have this problem, when I try to login in my wp dashboard (wp-admin) it redirects to a https connection.
when i type websitename.com/wp-admin, it'll show the login page but the url has is different. it says, websitename.com/login.php?redirect_to=https://websitename.com&reauth=1.
I never did anything odd, i was just install wordpress manually and later on this thing happens.
I am constantly forced to https, and just thought that I'd post here for anybody who may come across this in need of solutions
