Fatal error: Call to undefined function wp_get_current_user()
wp_get_current_user() is a pluggable function and not yet available when your plugin is included. You have to wait for the action plugins_loaded: Example: add_action( ‘plugins_loaded’, ‘wpse_92517_init’ ); function wpse_92517_init() { if(!is_super_admin()) add_action(‘widgets_init’,’my_unregister_widget’); } function my_unregister_widgets() { unregister_widget( ‘WP_Widget_Pages’ ); unregister_widget( ‘WP_Widget_Calendar’ ); } Or move the check into the widget function: add_action( ‘widgets_init’, ‘my_unregister_widget’ ); … Read more
