Hello,
I had a little look of your configuration and for a reason or another in your main configuration
Components => HikaShop => Configuration, Main tab and Order part
If your option Unpaid order statuses isn't set, as it was before.
Because, HikaShop before allow customer to pay check
unpaid status order, and if your order haven't a status that's won't works
thepetglider : melprok sent us backend access to check his HikaShop configuration, you can check the same point that has shown in the screenshot above.
Best regards,
