Hello,
You have definitively a modification in your views.
Even in the "working" page we can find the extra javascript code which generate the same error.
But because your "sp-smart-slider" is executed before, you do not see the effect of the JS error.
So I'm sorry but you do have custom code.
Maybe the HikaShop core file has been edited directly, I can't know and I can't tell. What I can tell for sure is that the JS code you have in not in the HikaShop packages.
