 * Hi!
 * I love this plugin, thank you. I know my WP version is old and must be updated,
   but:
 * I am getting a fatal error message when I try to include thumbnails:
    `"Fatal
   error: Call to undefined function has_post_thumbnail() in /var/www/vhosts/arttherapycentre.
   com/httpdocs/wp-content/plugins/list-category-posts/include/CatList.php on line
   258"`
 * Any idea?

 * Please, please, do some research. First you should read this: [http://codex.wordpress.org/Post_Thumbnails](http://codex.wordpress.org/Post_Thumbnails)
 * This is a very common problem, and it’s because your theme probably doesn’t support
   thumbnails. If you google for “Fatal error: Call to undefined function has_post_thumbnail()”,
   the first results show that you need to support this function in your theme to
   make thumbnails work.
