6 demo BO, on the other hand I could not scroll down to bottom of the side menu to access the module. This is due to by default the menu does not scroll, so you're able to't view the links to the bottom. There exists a totally free module accessible to https://www.presta-addons-modules.com/en/front-office/prestashop-currency-language-by-locations-geoip-auto-redirect.html
