Before asking question here I want to tell that I have already asked the question in stackoverflow and wordpress forum but have not got any answer. So finally I came here.
I have installed the woocommerce plugin in my wordpress 3.5.2. Everything is fine with woocommerce. I have made a folder called woocommerce and have pasted all the files inside the woocommerce template files inside my template folder. But there is something that I am totally stuck on. In the woocommerce checkout page I want to show cart totals in sidebar. But it is not showing there. In other pages it is working fine. So can someone kindly tell me what wrong here? Any help and suggestions will be really appreciated. Thanks
Update
Here is the screenshot for the woocommerce cart widget in sidebar which can be shown in all pages except the checkout page.
Edit:
Additional, how to make this change secure from updates?
