I am using Silverstripe version 2.4.9 I copied the folder newsletters (version 0.5) from an old project done in SilverStripe 2.4.6 where the module worked perfectly, but in the new project, the module does not work while I store the email from the form, the server gives me this error:

============ ERROR ==============================================

User Error] Member::generateAutologinHash is deprecated - tokens are no longer saved directly into the database in plaintext. Use the return value of the Member::generateAutologinTokenAndHash to get the token instead.

This is the function called by the template

......
$getNewsletter
...........

Page.php

public function getNewsletter() {
$newsletter = $this->Children()->First();
if ($newsletter){
$formController = new SubscriptionPage_Controller($newsletter);
return $formController->SubscriptionForm()->fortemplate();
// or return $formController->Form()->renderWith('Form', 'your customise form template');
}
}

Does anyone know help me?
Thanks in advance to all for the help.
