[shadeaustralia]

Hi,

My Magento Upgraded itself from 1.9.2.4 to 1.9.3 don't know how. But I'm getting error in loading configurable products pricing when select different combinations from the drop downs.

 Here is the error: 

configurable.js:286 Uncaught TypeError: Cannot read property 'changePrice' of undefined

reloadPrice @ configurable.js:286

configureElement @ configurable.js:137

configure @ configurable.js:121

Product.Config.configure @ swatches-product.js:60

(anonymous function) @ prototype.js:391

responder @ prototype.js:5598

Clear data, upgrade again. I have search your problem but nothing to see. Or you can try other magento upgrade guide.
