Hi,
The two links are coming from the same website, so the same HikaShop is used.
In the first one, there is a Joomla menu. That's why the url is SEF using the menu "shop-on-line".
The second link does not use a joomla menu, the SEF is the classical SEF way, using the "component hikashop" for the "product" ...
And because there is no menu, I think that's why the rest of the page is not displayed.
