I am using Joomla 3.4.5 and virtuemart 3.0.12, i downloaded the new onepagecheckout on the 5. December 2015.
I unchecked "onepagecheckout", and the "Use jQuery chosen for dropdowns in FE".
I checked "Must agree to Terms of Service on EVERY ORDER"
Disabeling the "Ajax for OPC" alsow didnt work
By the checkout there are now 2 problems:
1) When i use the coupon code and save it, at the end i confirm purchase i cant buy the product because it comes always the message "Your cart has been updated". So i have to go to the field and delete the code from the box, then it works. With ohther templates it changes the code from the box automaticly to the standard text and it works there. Perhaps it doesent refresh correctly.
2) If i change the number of pieces and push the refresh button, then it doesent show me the new kind of shipment, it makes the refresh only if i press the refresh-button a second time.
I hope you can find the solution, thank you
