Getting an undeserved error message on WooCommerce "Please choose product options…" -- 2

***FREELANCER MUST BE ABLE TO DO WORK RIGHT NOW> THIS IS URGENT BUT QUICK AND EASY JOB*** [login to view URL] On my WooCommerce Product page I am not allowed to add product to cart even though the product options have been selected. I get the message "Please choose product options…" This happens on VARIABLE PRODUCTS only. I only sell two products on my site right now, both variable products. I had a freelancer fix this two days ago but I cloned the site and Im having the SAME issue. The last Freelancer said he fixed like this: " i just changed the product permalink structure to Shop Base and then revert back to Default permalink structure and its fixed" I tried this "fix" and its not working! PLEASE HELP!! Thanks!
