Variations not working

After updating the WooCommerce plugin today, variations are not working and I’m not getting any errors. Products that don’t have variations are working fine.

Here is one page product as an example: https://skookummonkey.com/product/website-hosting-package-4-50000-mb-unlimited/

I already temp switched to the theme Twenty Thirteen and to Twenty Ten to see if it was a theme compatibility issue, and the same problem exists.

Here are my system details:
