No i have iOS 9 restrictions is not a thing but thanks

That is still in restrictions on my devices running iOS 9.2. Check for restrictions again: Use Restrictions on your iPhone, iPad, and iPod touch - Apple Support

If search didn't find it, and you don't have restrictions enabled try a home screen layout reset. Settings>General>Reset>Reset Home Screen Layout. -AJ

You are welcome.

That is the restrictions passcode. If you cannot remember it you will need to erase the iPad.

"If you lose or forget your Restrictions passcode, you'll need to erase your device and then set it up as a new device to remove the Restrictions passcode. Restoring the device using a backup won't remove the passcode."

To setup restrictions a passcode is required. Does anyone else use the iPad? If so, ask them if they set up restrictions.

You are welcome. I'm glad I was able to help.
