Woocommerce Variable Products not adding to cart

Hello, I’m having an issue where woocommerce variable products are not adding to my cart, unless I am logged in. I’ve found a bit of info about this issue on the woocommerce support page here: https://develop.woothemes.com/woocommerce/2014/02/solving-common-issues-after-updating-to-woocommerce-2-1/#variable-add-to-cart

This sounds exactly like the issues I am experiencing, but I don’t see any woocommerce files in the theme directory to disable, as the support page suggests. Is there something else that could be causing this issue, within the Dazzling theme files?

Thanks in advance.
