Bundled Products, Magento will not recalculate the Price – Bundle.reloadPrice()

Hello, I’m Tofu, nice to see you again.

My client gave me a purchased Magento template and asked me to install and configure a new Magento store for him. The template was very clean and professional. However, there was an weird issue since it did not support the latest Magento version 1.9.

I created serveral bundle products just for testing purpose then I added or subjected items to the cart, the price did not change. I got js errors:

Uncaught ReferenceError: taxCalcMethod is not defined 
Uncaught TypeError: Cannot call method ‘reloadPrice’ of undefined

Finally, I figured out the problem. We will need to copy the following javascript snippets from BASE theme to our activated theme in



Magento print errors: exception printing is disabled by default for security reasons

To print the errors on screen rename the local.xml.sample file in magento_root/errors/ to local.xml

These settings allow for errors to be printed onscreen.print-errors
