I have currently installed a fresh Wordpress on a dedicated server. It's the latest version with no plugins at all. Everything went successfully as always, I can see the website, but when I try to login through wp-login.php, no matter right or wrong data I'm inputting in the login form I receive "402 Payment Required" error! And a blank page, no reaction at all.
I'm checking server logs and there is no any php error either. I want to note that wp-login.php is not corrupt and is working, change password functionality which is part of that page is fully working.
