how to remove post published date, author name, filed under category name

Hello,

I’m sorry to hear that you’re facing issues with the meta tags displayed on your single post page after installing Rank Math. To remove the post published date, author name, and category names from your single post page, you can use the following code snippet:

add_filter('rank_math/opengraph/facebook/og_title', function ($content) {
    if (is_singular('post')) {
        $content = get_post_meta(get_the_ID(), 'custom_og_title', true); // Replace with your post meta.
        return $content;
    }
});

You can add this code snippet to your theme’s functions.php file. This will help in removing the meta tags that you mentioned from your single post page.

If you need further assistance or have any other questions, please feel free to ask.
