Question [Q] Rooting Problem Help!

So i've finished rooting my Note 2 N7105XXUEML3. SuperSU is not functioning, there's this security notice that keeps on popping up. My only guess is that it has something to do with knox? Anyhelp is appreciated, as i've got quite a few apps that needs root access

NVM i've got it working. But now touchwiz home keeps on crashing, mobile data keeps on disconnecting, and android media process(currently at 51%+) eats away my battery. I've got watchdog to monitor which apps uses a lot of cpu process. Does anyone know wth is happening?
