I’ve just updated WordPress engine to v2.5. I played with it for a moment and was very happy about it until I got this error when I went to WordPress Dahsboard:
Fatal error: Call to undefined function wp_register_sidebar_widget() in /XXX/wp-admin/includes/dashboard.php on line 31
Luckily, I’ve found a very simple solution on Tom Raftery’s Social Media Blog. Tom, thanks for sharing with others!
