Okay that was liek I said in my first answer, you fogot the :slug aprameter in your page urls in CMS/Pages. That's a common mistake, maybe I should make a more dedicated section in the documentation for that.
I've set your backend so it works now, you only have to manage your frontend views. Don't forget to make your own views in our theme or they will be overridden by the next update.
I also find that your related category link in product details sends secure urls, that is fixed in the last version. But in order to insall it you will have to set your Cms to use edges updates, or wait until I publish the last updates for everyone.
