I am sorry but we can't help you like that. You helper file is an HikaShop 1.5.5 file, not a HikaShop 2.0, so you don't have the latest version.

Your backend does not have such error with HikaShop. I can access to HikaShop backend features without any problem even if JParameter is used. I am quite sure that your template has overwrite the HikaShop helper file and added some errors. So I have reinstalled HikaShop 2.0 on your website and it solves the problem.
