Standard Image Effects like Anti-Aliasing and Depth Of Field "Not supported on this platform

Every time I try to add in one of the standard image effects to my camera it instantly gets turned off. I've gone through and tried to look at other people that had this issue, but I can't seem to resolve it.

I've even made a new scene, added Anti-Aliasing, and have it work fine. But if I copy over my Assets folder, go to the scene I'm working on and try to add the Anti-Aliasing script there, it errors again.
