Stockable Variants not working since upgrade

[futurefool]

I am developing a site on a xampp localhost. I am using Joomla 2.5.19 and was upgrading the development site from VM 2.0.22 to 2.6.0. Everything seems to work just fine apart from the stockable variant products. When I try to add a stockable variant to the cart the modal popup just displays a 0 and nothing is added to the cart. If I create a new stockable variant to the same parent product, this new stockable variant product can be added just fine.

Any ideas what could be causing this?

Thanks in advance.
