Tengo instalado el plugin "Flickr comment Importer" y alguna vez que he entrado en el panel de Wordpress me sale arriba el siguiente error:

<li> Your comments are imported when you're doing stuff in your WordPress backend and placed into the moderation queue. Make sure you login to WordPress often if you have a busy Flickr stream!</li>
