    If your following along with this and your using 2.0 framework, The Config class is initialized automatically by the 2.0 system so there is no need to do it manually. You’ll notice its not in the system/library folder also.

    Since the release of CI 2.0, you no longer can extend the class in the Library folder as was taught in the tutorial. If you want to extend a native library, you create the file in the Core folder, then follow the above tutorial.

    Please see: Extending the Class

      After further research, as of CI 2.1.3, there is no need to put the MY_file in the Core folder. They reverted it back to the way the tutorial states. Sorry to confuse, but after testing the 2.0 fix, I noticed that nothing was happening. I later found the correct fix.
