Featured Image doesn't show description

Hi there,

Featured images don't display Captions or Descriptions by default.
If you want to add the Description below the single post featured image then add this PHP Snippet to your site:

add_action( 'post_thumbnail_html', 'db_auto_single_featured_description', 10 );
function db_auto_single_featured_description( $html ) {
    $get_description = get_post(get_post_thumbnail_id())->post_content;
    if ( is_single() && !empty($get_description) ){
      $html .= '<div class="wp-caption">'. $get_description . '</div>';
    }
    return $html;
}

Adding PHP: https://docs.generatepress.com/article/adding-php/

Then a little CSS:

.featured-image .wp-caption {
  line-height: 2em;
  font-size: 0.8em;
  text-align: left;
}

Oh :) Thank you very much! I will try it!

Works great!

Greetings Kathrin

Glad to hear that!
