I understand that you have to submit Problem Set 0 to this address, http://cs50.edx.org/2015/psets/0/ . However, when I go to this address it immediately redirects me to this address, https://x.cs50.net/auth/ . This is a blank page that I can do nothing with. I would greatly appreciate some help solving this problem. ~Thanks

I think more people have this problem, don't know the reason though.

Try going directly to this url: https://x.cs50.net/2015/psets/0/

or: https://x.cs50.net/auth/login.php

This should let you acces the submission page
