Struggling - demo site link jumps to host server ?

Ok, I have put up a test site: www.nutraseries.com

I installed and configured hikashop starter, you can see the menu link on the first page

But when you click this:

https/nutraseries.com/index.php/Nutraprime-Products/product/listing/Itemid-546.html

you end up at my host server angryhosting.com

instead of getting this result (which I obtained by cutting and pasting out the reference link generated from the admin area):

http/nutraseries.com/index.php?option=com_hikashop&ctrl=product&task=updatecart&quantity=1&checkout=1&product_id=1

SO

something must be up with SSL. Can anyone help me? Do I need to somehow put an SSL cert on my site or some such thing?

Its not an SSL thing apparently, I don't have SSL enabled anywhere

so why is https: coming up ? HELP PLEASE

Of course if you try the URL nutraseries.com/index.php/Nutraprime-Pro...ting/Itemid-546.html and that you didn't setup SSL on your website, it won't work. You should use the same URL without SSL like that:
nutraseries.com/index.php/Nutraprime-Pro...ting/Itemid-546.html
That one works. And that's the one you actually have on your website front end.
