Restart your iPhone, iPad, or iPod touch - Apple Support

Try restarting it: hold power button down until "slide to power off", power off for 10 seconds, press power to restart.
if that doesn't fix it, reset your iPad: hold BOTH power button and Home button until device resets and apple logo appears.
