Order status defaulting to 'none'

If the status is "none" in the created orders, it means that the status which was added to the order could not be found by HikaShop in the list of statuses that you can find in the menu System->Order statuses.
One explanation is that you changed some of these statuses.
Another one is that the order status in the "Default order status" option of the configuration does not exist anymore in that list of statuses.

So I would recommend to double check that list of statuses as well as the status options of your Hikashop configuration and of your payment methods

Could you edit an order and do a screenshot of the "history" area ?

Also, can you check the options of your payment plugin for the order statuses options ?
