Internships aren't easy. They require a lot of hard work, dedication, and patience. Things may not pop off immediately. You may be picking up coffee and lunch orders for the first few weeks or months, but if you work hard, it'll change. But you have to work hard. Ask how you can contribute and what you can improve on without being a pest. If there isn't an immediate task at hand; think of something that's been sitting on the back burner. It's up to you to show these editors they should be assigning you something and not giving the task to someone else.
