Hey stenaus,
Just to clarify, changing the localization setting won’t actually translate your Facebook post content into another language, it only translates the text that Facebook adds. So for example, if you share a photo then Facebook adds some text which says ‘Stenaus shared a photo’. If you change the localization to another language then this text is translated into that language. If you write your own content in the post then it will be displayed in whatever language you write it in regardless of what the localization is set to. If you want your posts to be displayed in a different language then you’d have to write them in that language when you create the post on Facebook. If you write them in English on Facebook then they’ll be displayed in English on your site.
If the localization setting isn’t changing the Facebook text as described above then if you send me a link to the page where you’re displaying the feed then I can take a look.
Let me know whether that makes sense.
John
