Website is www.knockoutnutrition.com.au Thanks

So I am never a fan of upgrading things but thought I'd update from 1.5 to 1.6. After doing this I had all sorts of issues which I seem to have figured out most. But the following I'm stuck: -Product prices display in main screen but once into the product page only display $0, how can I get it to display thrifty price in the product page -my image slider no longer works -on mobile site, checkout button at bottom of screen does not work. So there is no way to get to your cart unless you add another product and quickly click checkout. Please help with any ideas to fix these issues. Hoping it's an easy fix as I'm now starting to regret the upgrade, but want to make it work. Thanks
