I am setting up my site to use zencart ver 1.5.4. I currently us oscommerce. I have zencart set up in a different directory on the same server.

I was able to upload all my products by matching the db structure of zencart and using easy populate.

Everything looks good except:

In admin. All my categories show. Click on a category and the products show. Click on a product and I get error 404 not found.

On front end. All looks good. Categories show fine. Click on a category and the product listing shows. I can even add to my cart from here and it shows in cart. If I click on the product to go to product description, I get page not found 404 within my site.

I don't know where to go from here. I have searched the forum and google and found no help.
