In local variants all working
I do not understand what I'm doing wrong.

https://www.nopcommerce.com/boards/t/10664/nop-2-fresh-install-object-reference-not-set-to-an-instance-of-an-object.aspx

I made all as in http://www.youtube.com/watch?v=8E8G0CUh4S8
But on  host I uploaded from Webmatrix using protocol Ftp because  protocol "Web deploy" don't support host.
If I run site from directory   Deployable\nop_2.0 using Webmatrix - I'm getting error

Can you help me.  What I'm doing wrong.

Everyone who got an error, make in TaxService.cs
            var activeTaxProvider = LoadActiveTaxProvider();
            if (activeTaxProvider != null)
            {
                //get tax rate
                var calculateTaxResult = activeTaxProvider.GetTaxRate(calculateTaxRequest);
                if (calculateTaxResult.Success)
                    return calculateTaxResult.TaxRate;
            }
            return decimal.Zero;

        }
after line 233.
And all right!!!
