Do you often have a registered customers but you didnt notice them? Perhaps its because default prestashop didnt support this feature.

In order to enable this feature, you must do a little tweak to your prestashop files. Heres how to do the tweak.

1. Backup authentication.php file
2. Open the authentication.php file, and go to line 95, at the start of the else clause and email is sent to the customer with their details.

Change the following code:

if (!Mail::Send(intval($cookie->id_lang), 'account', 'Welcome!',
array('{firstname}' => $customer->firstname, '{lastname}' => $customer->lastname,
'{email}' => $customer->email, '{passwd}' => Tools::getValue('passwd')),
$customer->email, $customer->firstname.' '.$customer->lastname))
$errors[] = Tools::displayError('cannot send email');
