Hello,
If you take a look at your browser console ; you will see that the ajax calls made by HikaShop gave HTTP 403 errors.
These error code are not coming from HikaShop but by a third party plugin/component/system.
I don't know what you have installed in your website and how the security is made ; but there is something which do not allow HikaShop to perform that ajax call.
Regards,
