We'll need more information to help you with that. What device and android version do to you have? Is that happening just with WhatsApp or with all your apps?

If you're running Lollipop go to settings - sounds & notifications and make sure you don't have disabled them in "when device is locked". Also, in that section check the app notifications for WhatsApp.
