Ussual odoo ecommerce process is: 

- /shop/cart (here is where you add products to cart)
- /shop/checkout (here is where you select shipping address)
- /shop/payment (here is where you select delivery and payment methods)
- /payment/process (page goes blank here with Payment Process text shown)
- /shop/confirmation (here is where you informed with Sales Order number)

but recenty, my odoo does not show /shop/confirmation page. It went straight to home page after Payment Process text shown in a blank page. I can not see Sales Order number, I have to open /my/orders or my email to see the SO number. Is there any settings or condition that describe this situation? I want to /shop/confirmation (Sales Order number) is shown after payment process.
