Как убрать open graph из плагина?

Hello,

Thank you for contacting Rank Math.

You can use this filter to remove the Opengraph tags:

/**
 * Hook to remove og:tags
 */
add_action( 'rank_math/head', function() {
	remove_all_actions( 'rank_math/opengraph/facebook' );
	remove_all_actions( 'rank_math/opengraph/twitter' );
});

Here is a guide you can follow to add the filter:

Hope this helps.

Thank you.
