Hi
The fact that you see the same amount for both currencies simply mean that you've configured a rate of 1 in your currencies. Go in the menu System>Currencies and click on the "update rates" button in order to get the rates of the currencies.
The exact name of the option is "Show price in original currency". You can find it in the "Default parameters for products" section of the Display tab of the HikaShop configuration. And similarly in your modules/menus settings.
I went to check your website again and now I see the prices in $ only. So it seems that something changed again on your website.
I also get that error:
cURL failed. Error: connect() timed out!
API returned error:
So it would indicate a problem with either the configuration of the geolocation plugin, or your web server not allowed to make outgoing connections to the geolocation server.
