Glitch?

I can neither log in nor sign up for an account. It gives me contradictory messages whenever I try to reclaim my password or create a new account. Its been doing this for months, please help. If I try to say I forgot my password, it tells me that theres no name associated with my email address, but when I try to make a new account, it says that my email address is already being used. I have screenshots.
