Hi,
I've created a new project with four pages: shop, cart, checkout, invoice (with respective widgets).
I have an offline payment method setup and all the required store settings.
No product or type were deleted or modified.
when i check out - after preview - i get the following error:

Object reference not set to an instance of an object.

Hi Lev Rosenblit,

I tried to recreate the error that you are seeing. However, I was unable to get the exception that you posted using the configuration described in your post. Could you provide me with more details so that I can recreate the error.

Hey Freddy,

I'm not sure what solved the problem exactly for Lev, but judging by the error message displayed I'm guessing the tax class, tax rates and/or ecommerce configuration> tax display mode isn't configured.

First you need to set up tax classes. Then apply tax rates to those classes and finally in the configuration set how the store should display them. (Excluding Tax or Including Tax. And in case of Including tax, which tax should be displayed).

Hope this solves your issues.
