[quote author="InsiteFX" date="1298181588"]Any Class that is in th systen/core directory that is extened has to be placed into the application/core directory. These are Core Classes.
MY_Controller is extending the system/core/CI_Controller, as you can see this is a Core Class.
Any Class that is extended that is in the system/libraries directory has to be placed into the application/libraries directory. These are Library Classes.[/quote]So would I be right in assuming the previous versions of CodeIgniter, prior to 2.0.x were quite relaxed in their handling of this hierarchy?
As I said, I'm working in a 1.7.x version and I have the MY_Controller in the application/libraries folder and it's working just fine.
