Hi,
1. Guest checkout is a feature of commercial editions of HikaShop.
Even if you can remove the "login" step from your checkout ; you will also need to remove the "address" step and it means that you won't have any single information about the user (like an email to contact him or send him the notifications).

2. For what I saw in your checkout, you need to be logged in order to continue in the checkout ; otherwise you won't have the "next" button.

By the way, do not send me private message, use the "contact us" form instead.
