products not showing in categories after upgrade

I just upgraded one of my sites from 1.3.5 to zen-cart-v1.3.7.1-full-patched-07052007. Everything went smoothly, with one exception. After uploading my products, they do not show up in the categories.

Everything is 100% ok in my database. All product info is there. For some reaseon, my cart is not retrieving the product information.

Oddly enough though, in the new products sidebox, and new products for the month, the product images and price shows up. But, if you click on the image, it tells you the product cannot be found, and if you click on a category, it says, There are no products to list in this category.

I'm completely stumped:frusty:

DOOOOHHHHH!!!!!!:oops:

I figured it out. I left out the names column in my upload. Once I added the names, the products showed up.
