Nostalrius Begins - Quality wow vanilla realm (1.12)

When i go to https://en.nostalrius.org/password i get a white page that says No input file specified

Can anyone explain to me what that means? Is password reset down or something atm?

It also looks like we won't be able to make a new account before the shutdown. A real shame, considering I would love to play it again and re-live the experience one last time.
