Notifications and control panel do not work on either the app screen or home screen
On my home screen and in apps, I can not swipe up or down to release the notifications or control panel. It has worked earlier today, however not any more.
I can, however, access them in the lock screen, andin settings, they are allows to open in apps. It should always allow me to access them in the home screen though, so I do not know what has happened.
What do I have to do to access the control panel in the home screen, and why is it like this?
iPod touch, iOS 8.1.3
