3) If you have problems with translation of default WC pages to other language and use the third-party plugin to create the multilingual site you need to contact Polylang plugin support to get instructions how to translate pages using their plugin. We are able to help you if the problem is caused by our theme only. What does it mean? It means that if you use any default theme (Storefront, Twenty Sixteen etc) and you made translation and everything works fine but once you enable XStore you don’t see the correct translation. Then we’ll be able to help you. But if you can’t translate your site even with the default theme we can do nothing.
