My french store (a testing site) is calculating the wrong tax in shopping cart, but right in backend panel, in Manage tax rate, the french store rate is set to 20, for example, if the price is 139, the right tax should be 23.17 (my production site is showing 23.17 as same as i see in backend)
The shopping cart should show the tax amount as same as i see in backend (23.17 but not 27.8), anyone know what is the problem?
