Import Stopped Working/No Products Found

A week or two ago my imported products from my Cafepress store are no longer importing, my page now just says no products found and my error log produces an error for each product not showing. Never had any issues before and can’t figure out why this is no longer working. I double checked everything on my store is still showing properly. Any ideas?
