I try to reconstruct.
1. Main tax zone -> on the Configuration / Main "-> Uzbekistan
2. Tax zones -> on the Configuration / System / Zone -> Uzbekistan
3. Tax category -> About ".../ System / Taxes / tax management categories "-> create category" Test Uzbekistan "
4. Tax rates -> About ".../ System / Taxes / Manage-rates-New "-> rate to create" test 50% "
5. Tax rules -> ".../ System / Taxes / New "
- Tax category = Test Uzbekistan
- Rate = 50% test
- Zone = Uzbekistan
- Customer type = All ...
- Published = yes
I only have "tax rule - Uzbekistan" active -> negative
I clicked on "Shipping" when you -> negative
Have I forgotten anything? Joomla + Hika) rebuild with MSIE? If it is the browser, it will probably be faster.
Have I understood correctly?
Main tax zone -> Tax Zones Tax category-Tax Rates
Main tax zone -> (tax rules)
I still get no field for a tax and I can choose the product page for the "tax category" "UST Umsatzsteuer". This category is deactivated so the "Manager tax categories".
