I've been using the Advanced Cross Sell module for a few months and all was working fine. However, yesterday when I tried to cross sell two products it's not working.
I get a No Product was Found with the model: # (number here) error for both products.
Product Model numbers are correct: both products are in the store and working. I even tried to cross sell "old" products to check the functionality and it's giving me the same error message.
Any suggestions?
