It seems that the latest release of Magento 1.9.3.X breaks old theme due to javascript codes missing.
You may have the following errors :
TypeError: Product.OptionsPrice is not a constructor TypeError: optionsPrice is undefined TypeError: bundle is undefined TypeError: bundle is undefined
The default RWD ((Responsive Web Design) theme is working as expected and the problem is into my theme..
You should check yours if you are using bundled products.
I will work to create a new theme.
