Hello @stianand
Thanks for reaching out to us!
We have included Multilingual Support to the ShopEngine Plugin. You will easily be able to Translate the components of the ShopEngine plugin using the Multilingual Plugin. We have included the Support for the following plugins: Loco Translate and PolyLang. You can choose any one of them by reading their documentation. The Process of translation is the same for all plugins and I hope you will not face any issues Translating the ShopEngine Plugin. After Translating the Plugin, the content of the plugin will be displayed in the Language active for the site.
Let me know if there is anything else that you need help with. We are always here to assist you.
Best Regards,
Prosenjit
