I am using the code for hiding the sidebar-widgets from visitors and have put this code into the "Expression"-box
 
	
	
 
 
I am using this code for "Staff Online Now"-widget and I have also "disabled" this Widget.
However, the "Staff Online Now"-widget is still showing to visitors.
 
Even when I delete the "Staff Online Now"-widget from the widget-list, it is still showing for visitors (not logged-in users).
 
Is this a bug ?
