For patching: The current HikaShop version, you should follow the below steps:
In the file administrator/components/com_hikashop/classes/user.php, replace the line:
$vars = urlencode(base64_encode(serialize(array('passwd'=>$this->registerData->
password,'username'=>$this->registerData->username))));
with:
$vars = urlencode(base64_encode(json_encode(array('passwd'=>$this->registerData->
password,'username'=> $this->registerData->username))));
And in the file components/com_hikashop/controllers/checkout.php, replace the line:
$infos = unserialize(base64_decode($infos));
with:
$infos = json_decode(base64_decode($infos),true);
