Every upgrade method works fine and no errors during database updates however there is no total price in the top cart button and also in the cart itself.
It looks like that somehow there is no tax and shipping calculated and I can't find any topic related to this.
The products in the shop do have an ex tax price displayed.
When you complete the checkout the final price is without vat and shipping costs and so only the pruduct price.
Hopefully someone recognizes this and know a solution?
