Greetings,
I followed the instructions from a much older post on this and put code into the the functions.php file and there was no change. What I would like is the user name of the member who owns a gallery or media to appear und the thumbnail. I am creating pages that gather galleries across members, so I want visitors to see who the media belongs to. These pages are created with shortcode.
This is the code I added

add_action( ‘mpp_after_media_widget_item’, ‘mpp_custom_add_user_link’ );
function mpp_custom_add_user_link() {
//you may put some conditions here like

//mpp_is_single_gallery();
//mpp_is_single_media();
//to avoid showing it on single gallery/media pages

$user_link = bp_core_get_userlink( mpp_get_media_creator_id() );
echo $user_link;
}
add_action( ‘mpp_after_media_shortcode_item’, ‘mpp_custom_add_user_link’ );
