I have a few problems after upgrading from Magento 1.6.2 to 1.9.2.1 that I don't seem to get an answer to on other forums or on my own:
1. When I select an option with a product (https://sportinngerritsen.nl/outlet/msv-rebound-200-mtr-parelmoer-wit-2211) the price changes to 0.00. I tried copying files from my test environment (http://sportinn.portalserver.nl/outlet/kirschbaum-p2) to the production environment, since I fixed this on my test environment, but unfortunately that doesn't work..
2. Shopping cart price rules stopped working.
When I do this it works (this gives stops items from calculating shipping costs when the price is equal of greater than 100):
If ANY of these conditions are TRUE : Subtotal equals or greater than 100 If an item is FOUND in the cart with ALL of these conditions true: Category is one of 93, 94, 95, 97, 99, 98, 96
But when I use this it doesn't work (this shouldn't calculate shipping costs for some products in categories):
If ANY of these conditions are TRUE : Subtotal equals or greater than 100 If an item is FOUND in the cart with ALL of these conditions true: Category is one of 93, 94, 95, 97, 99, 98, 96 If an item is FOUND in the cart with ALL of these conditions true: Category is one of 24, 93, 94, 95, 97, 99, 98, 96
I have some more problems, but these are the most important onces at the moment.
I moved your topic to the Technical Issues section for Magento 1.x as you posted it in the section for Magento 2.
Did this ever get resolved? I'm having the same problem...
