Using latest version of NOF 13.

My ecommerce ground to a halt and when I checked my online store, the "buy" and "add to cart" buttons disappeared.

I checked my configuration and made sure both buttons are selected to be visible. I also double-checked the paths to the buttons. Everything is proper.

This all happened sometime last week without me changing anything to my online store.

Any ideas how to get them back?

Thanks!
Fred
