# It isn’t generated.

 * The thumbnail size changed suddenly.
    All thumbnail size became full-size. I 
   deleted thumbnail reluctantly.
 *     ```
       global $wpdb;
       $wpdb->query( "
       	DELETE FROM $wpdb->postmeta
       	WHERE meta_key = '_thumbnail_id'
       " );
       ```
   
 * After that it was generated by a plug-in.
    But it isn’t generated.

 * I can confirm this. It says has generated, the postmeta are there, but the media
   entries in posts table are not.

 * I think because it relies on wp-image-xxx but in my case the blog was imported
   and for some reason all the media xxx didn’t exist.
