Passwort reset state's "undefined" and lock's the user

Hi hi,

for testing purpose I just tried to reset my user's password. Beforehand I checked that the smtp settings are correct:

$smtp_email_settings = array(
      'host'=>"cloud.my-domain.de",
      'username'=>"user",
      'password'=>"pass",
      'from'=>array('noreply@edm.my-domain.de' => 'EDM - ONE Energy-IT GmbH')
    );

When I enter an username and an email all I see is "undefined", when I try to relogin afterwards emoncms tells me "Incorrect password, if your sure its correct try clearing your browser cache"...

To get back on to the system I registered a new user and altered his passwd and salt string from the DB with mine, so there's no urgent prob. But I'ld like to have that working too...

Hope you can help.
