meta cards are showing author name for all pages

Hello,

Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.

Please head over to your WordPress Dashboard > Rank Math > Titles & Meta > [Post Type] and from there disable the Slack Enhanced Sharing option:

However, since you’re facing this on Discord, we do not have an option to disable this from the settings. You can try the filter in this thread and see if that fixes the issue: https://wordpress.stackexchange.com/questions/369151/how-to-remove-author-name-and-link-from-a-shared-link-preview

Here’s the code from the thread:

add_filter( 'oembed_response_data', 'disable_embeds_filter_oembed_response_data_' );
function disable_embeds_filter_oembed_response_data_( $data ) {
    unset($data['author_url']);
    unset($data['author_name']);
    return $data;
}

Here’s how you can add filter/hook to your WordPress site: https://rankmath.com/kb/wordpress-hooks-actions-filters/

Let us know how it goes. Looking forward to helping you.
