Deleted menu still appears on front end
				
				
                
                    
                    
                
                
                    
						
                
                
                    I created a menu, and assigned it to location "primary menu".
Later, I moved one of the elements to be a child of another element, but this change did not show on the front end.
Later, the client requested I remove the menu, so I deselected "primary menu" as the location of the menu, but it still showed on the front end.
So, I deleted the menu, but it is still showing on the 
front end.
Why is this occurring?  We have no caching plugins installed.
