Problem after upgrade application to CodeIgniter 3

Question

I just upgraded my CodeIgniter from version 2.2 to 3.1.10. I replace system folder and its contents and rename all controller name to capitalized and everything else needed. Then I got this error:

A PHP Error was encountered
Severity: Warning
Message: Declaration of MY_Router::set_directory($dir) should be compatible with CI_Router::set_directory($dir, $append = false)
Filename: core/MY_Router.php
Line Number: 0

Inside application/core there are some files:

MY_Route.php
MY_Input.php
MY_Controller.php
etc

UPDATED: here is a piece of code in MY_Route

function set_directory($dir)
{
    // Allow forward slash, but don't allow periods.
    $this->directory = str_replace('.', '', $dir) . '/';
}

I'm sure that the problem is caused by these files but I have no idea what to do. I read the documentation how to upgrade but no clue about this problem. Anyone can help me please?

post the code from core/MY_Router.php, the set_directory method — Binar Web

Maybe help you. You need add argument:

function set_directory($dir, $append = false) <-- edit
{
    // Allow forward slash, but don't allow periods.
    $this->directory = str_replace('.', '', $dir) . '/';
}
