Answer 3

You can read the description of your error, it said that some functions in MX_Loader class is not compatible. It is not compatible with the parent class.

My MX Class extends CI_Loader, which is the CI Core loader. So just find the mentioned function in the error message and find it in the Core Loader. You can find it in system/core/loader.php

For example, the error number 1 has library function error. Just find "library" function in core loader and copy the parameter inside the function to the parameter of the library function in your MX loader. And so on
