Great, thanks for the explanation.
1 - For the Add to cart, I selected 'Always stay on the same page'. Should I at least get a system message to confirm the product has being added to the cart? I just want to confirm, if it should be should be coming app with a system message then it is a template problem that I will check.
2 - I have changed all the setting as you recommended, but the content module still loading mootools. Is there any thing I am missing?
Configurations/Display - Use bootstrap design: Yes, Popup Mode: Bootstrap, Use Chosen library: Yes, Image popup mode: Shadowbox (external), Add to cart: Alway stay on the same page.
Thanks, for the the details.
Cheers
