No registration for new users

Test site
HikaShop version -- : 3.2.1
-- Joomla version -- : 3.2.2
-- PHP version -- : 5.3.2
-- Browser(s) name and version -- : Tested on newest Versions with IE, Chrome, Firefox

Hi all,
after upgrading from 3.2.0 to 3.2.1 of Hikashop, users are no longer able to Register during the checkout process. If I put in the users Details and click on submit, System brings me back to the Homepage and tells me that the cart is empty.
Registering in Joomla itself is working fine.
Many thanks for your help in advance.
Best regards
Torsten

Hi Nicolas,

sorry for the late reply, I did a reset with Akeeba Backup to the previous version of Hikashop and it was working then.

Best regards
Torsten
