How to change meta property=”og:locale” without changing site language in WP.

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention.

You can this filter to change the og:locale on your site:

/**
 * Allow developers to change the content of specific social meta tags.
 *
 * The dynamic part of the hook name. $network, is the network slug
 * and $og_property, is the property which we are outputting.
 *
 * @param string $content The content of the property.
 */
add_filter( "rank_math/opengraph/facebook/og_locale", function( $content ) {
        $content = 'da_DK';
	return $content;>

});

And here’s a link on how to add a filter to your website:
