Merhaba, sorun nasıl çözüldü acaba ?
fucntions.php en altına bunu ekleyin.
function thumbnail_in_rssfeed($content) { global $post; if(has_post_thumbnail($post->ID)) { $content = '' . get_the_post_thumbnail($post->ID) . '' . $content; } return $content; } add_filter('the_excerpt_rss', 'thumbnail_in_rssfeed'); add_filter('the_content_feed', 'thumbnail_in_rssfeed');
