I've just installed a fresh install of YaBB SE 1.4.1 on my server. There were no errors during the install, and I can view my board.
However, when I try to login using either the form at the bottom or the login page, I get "An error has occured!", and the error is "You should fill in a username."
Of course I filled in the username and the password, so the error message seems rather odd. The same error message also occurs when I try to register a new account.
Does anyone have any ideas? The board address is
http://link.idlegames.com/j2hg/YaBB if you wanted to look at it.
Server details:
PHP Version 4.2.3
