Hello
i updated to nopcommerce 1.8 and i have some problems fixing the tax rate on my site .

I want to have one and only tax . I selected fixed rate tax provider , but I can't set there a tax globally for my site .
I can only set tax for tax category , but none of this categories i associated to any product .

How can I do that ? Am i missing something ?

Nop 16 had as I remeber a fixed rate for the tax that was active for all products , can this be done in 1.8



Thank you in advance
