Upgrade broke my shop

I just upgraded and while most things seem to work correctly, the "add to Cart" button is missing. I use HikaShop on another site that had the latest upgrade and I have checked out the modules, menus etc and I cannot find where the problem is.

PLEASE HELP!

Thanks and appreciate it,
Miss Mary

my website is: www.thenorthpolepress.com

Go in the configuration and make sure that the "display add to cart buttons" option is turned on and save the configuration.
