Embedded Facebook is in wrong language

Hello,

When I insert posts from Facebook they appears in weird language.

Example

How/where to change this so it shows in the same language as a website?

Regards,

Theme does not control embedded Facebook posts, as that is loaded via Facebook, and via the OEMBED built in to WordPress. Probably one option is to ensure you manually add the language your site is actually in, within the wp-config.php file, especially if not default “english”…

Language of FB embed is usually based on the person viewing the site browser setting, or in some cases the language of the original FB post with option to translate.

( I don’t work here .)

Thank you Chris. I think that was the case until wordpress ver. 4. Now it appears define(‘WPLANG’, ”); is depreciated. I selected my site language in ‘Settings>General’.

In the source of posts I have found this:

<script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/ar_AR/sdk.js#xfbml=1&version=v2.3"; fjs.parentNode.insertBefore(js, fjs);}(document, 'script', 'facebook-jssdk'));</script>

I believe that if I manage to change ar_AR to my website language that would fix the issue, however I have no idea where to change it.

I still need help with that.

Thank you guys,

I added this:
add_filter( 'the_content', 'facebook_sdk_replace' );
function facebook_sdk_replace( $content ) {
if ( is_single() ) {
$content = str_replace("/ar_AR/", "/pl_PL/", $content);
}
return $content;
}

and embedded Facebook is showing in the same language as my site.

Where did you add the code?
