Hi,
The link at the top of the page is the link for the same page. In case of you want to reload it so there no access to a file outside of joomla.
You should have a wrong link or a wrong redirection in your website/hosting. I don't have enough information to give you a precise answer.
But HikaShop, by default, is working good so it can't be something where I can say "change this file at this line to fix the problem".
