WP Ecommerce Price Variation isn't updating the price

Hi,

I am encountering this problem now, and believe others may also facing the same issues. Those who are good at WP ecommerce (3.8.11.1), please kindly help. Thanks in advance!

The problem now is: WP Ecommerce Price Variation isn’t updating the price. At the product page, the price only shows “from $xxx” after the selection of the relevant variation.

And the Ajax message box which prompts and ask “whether you want to check out now, or continue shopping” disappears.

However, when I tried to “add to cart”, the cart price is correct. And the shopping cart can update.

I am guessing the Ajax conflicts with something. but I am not sure.

Anyone encounter the similar problem? Please help! Thank you very much!!!
