Why my payment page got bypass or not showing?

There is several reason why your payment page is not showing:

1. There is no payment method in your store.
2. You have activated bypass payment page settings
3. One of your product setting's is "Display as estimated price"

2. De-activate bypass payment page settings (from Settings > Checkout)
3. Find all products that have "Display as estimated price" and de-activate this setting.
4. Have any order total amount bigger than $0
