I’m having the same issue, but the variation in my case is price and I’m not getting any errors. It’s simply not working.
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 to see if it was a theme compatibility issue, and the same problem exists. All non-variable items are working fine.
Here are my system details:
