[Plugin: Query Posts] Thumbnail error message
I am using the newest WordPress 3.0.1 and BuddyPress. This Query Posts plugin works fine as long as the thumbnail option is switched off. If I switch it on, following error message appears:
Fatal error: Call to undefined function the_post_thumbnail() in /……../wp-content/plugins/query-posts/widget-query-posts.php on line 166
