[xwiki-users] Creating new users

Hi everyone, Basically new to the xwiki scene, so forgive me if this is a painfully obvious question. I'm trying to create new users, and the registration form keeps giving me a "passwords are different or password is empty" error. I've tried many different passwords of varying length and complexity, and the error is the same. When I attempt to register a new user from an unlogged-in/anonymous viewpoint, it throws a different error: "registration has failed due to unknown reasons (Error code: -1)". This is a new wiki and I haven't done any significant configuration beyond the default settings. It's hosted on xwiki.org. Any thoughts?
