today I suddenly found a serious magento bug in my website. in all my product pages front end, if I have options for different price then no matter what option I selected the product only shows a fixed basic price, no matter the option + or - how much money, the product price always doesn't change. but if I add different option to shopping cart and go the cart page, then the price can display differently as normal. It didn't work like this before. Different options should show different price immediately but no need to add to shopping cart and check in cart page. Please Kindly advice what should I do and can you help me to fix that ? For example this product(all products in my website has problem): https://www.xicart.com/english/front-outer-screen-glass-lens-with-pre-installed-oca-for-samsung-gala...
My magento version is ver. 1.9.1.0
