The 'Site Language' setting affects small pieces of system text that your visitors see in your site's blog, the Simple Blog subscription feature, Simple Store, and social feed sections - e.g. "Return to site" button for blog, "View More" link for social feed, Simple Store's buyer flow and email notifications to buyers.
** This feature will not change any of the content you've entered!**
To change your Site Language, go into your editor's Settings panel, select "Basic Info", and then Site Language. You'll see the window below, in which you can choose from 13 languages (other than English).
Select the Site Language that matches your site content, and click "UPDATE". Once you republish your site, the Site Language change will be reflected.
