@Jorgen, i know that warning is not high priority for the team, but i always display warnings when i do test or after updates, a warning is most case an error.
This is not important for standard PHP render, but for an E-commerce, i think, this is more important because the shop continue to work with bad values with possible errors on calculating price for eg. displaying unknow values ...
So yes in all other situations, this is unimportant but for VM(or any shopping solution) i think this is priority number 1 to have a safe & working shop!
