# unregister_widget throws error

 * I want to remove some of the default widgets since I don’t need them and I don’t
   want to confuse people using the Administration section that these widgets have
   an implementation.
 * I’m using the “unregister_widget” function defined here: [http://codex.wordpress.org/Function_Reference/unregister_widget](http://codex.wordpress.org/Function_Reference/unregister_widget)
 * But when I call it, e.g., to remove the Categories widget (or any other for that
   matter), it throws and error:
 * unregister_widget(‘WP_Widget_Categories’);
 * Results in:
 * Call to a member function unregister() on a non-object in wp-includes/widgets.
   php on line 451
 * Any help, or other approaches to remove default widgets, would be much appreciated.
