NEXT AND PREVIOUS ON PRODUCT PAGE

I want to use a back or previous button and a next or forward button on my product page. Have read that this is a feature of breadcrumbs. Read that make sure breadcrumbs is enabled for all pages and set to simplified breadcrumbs. Can not find where to set simplified breadcrumbs. Is there a better way? I am using starter perhaps not a feature in this version.

The "next" and "previous" buttons can be enabled in Config > Display > Default parameters for products, "Show shortcuts to other category products".
And it's available in the starter edition.

The breadcrumbs options are in Config > Features > SEF url option

I am not showing either of these options, perhaps another feature needs to be toggled first? see screenshots .I have searched to no avail. Thank you

That's because you're using an old version of HikaShop where that option was not implemented yet.

You will have to update in order to activate that option.
