Woocommerce "File not found"

I am using Woocommerce and I create a Product with description and images, but when I check on the listing of products and click on View Details, I get File not found with Sorry, but we couldn’t find the content you were looking for. I’ve increased the memory, but I am missing a step because I don’t see the change in my settings.

I would be happy to ignore the Listing of Products and find the way to add directly to the cart, but I have tried various ways ?add-to-cart id=6078, and that doesn’t work either.
http://attunementdeck.com/cart/?add-to-cart id=”6078″ sku=”EAD-2″ I tried it with and without the sku.

Any assistance would be appreciated.
