I always appreciate free extensions and this one looked promising.r free extension RokQuickCart, but what is it good for if it is not updated?
As previous user mentioned in their reviews, I can confirm that the Checkout button is not working on Joomla 3.3.x
It has been also tested on IE 11, Firefox 32.01, and PaleMoon 24.7.2.
By clicking on the checkout button, nothing happens. I noticed Rockettheme about that, but it seems they do not care. Looks like it will be a graveyard component.
