Since i have upgraded my entire class script is buggered up.

Call to undefined function: _crypt()

here is the snippets

function login($username,$password,$remember,$page){
$this->db = $GLOBALS['db'];
$this->password = $this->_crypt($password);
$this->_check_username($username);
$this->_check_password($username);
$this->_is_confirmed($username);

if ($this->username_result && $this->pass_result && $this->confirmed_result){
$this->_setSession($remember,true);
	redirect($page);
//return true;
	}
else
	// login/pass check failed
	{
	$this->logout($_SERVER['PHP_SELF'].$this->_build_errorquery($this->result));
	}
  }

//pass password :: private
function _crypt($password){
	return md5($password);
}


i cant honestly see what the reason for this is, i suggest its a bug , as my script was working before , what is even more wierd , my function was called _encrypt it wasnt working so i changed it to _crypt and it started working fine , i have reloaded my page today and its back to the same error.
