Total price is not right (after upgrade)

[appletree]

I have made a VM shop on a test server (VM 2.0.14) and made a backup (with Akeeba)
The backup is placed on the site of customer and VM updated to 2.0.20b.
I also have used template overrides for the shoppingcart. First I saw that one map was missing ((html/com_virtuemart/cart/) so I copied that one to new server.

Problem:
But the total price of products in shoppingcart is not right, the 21% VAT is not plus but minus.
The old VM version on test-server is doing it right (total price € 161,-)
The newer version on live-server is wrong (€ 119,-)  What is the solution?

Also other products has the wrong prices.


Live server:  Joomla 2.5.9  VM 2.0.20b   php 5.3.23  Apache
Test server: Joomla 2.5.7  VM 2.0.14     php 5.3.17  Apache
