Why is my particular controller not working in CodeIgniter 3.0?

Question

I'm new with Codeigniter and this is the first time I encounter this issue. I have a project that has many models, controllers, and multilevel views. All, but one of my controller is not working. I'll try my best to explain my issue.

Let's say I have controller A and Controller B.

Link from view to access each controller:

//This link go to Con A
<a href="<?php print base_url(); ?>ConA/user">TEST1</a>

//This link go to Con B
<a href="<?php print base_url(); ?>ConB/user2">TEST2</a>

Con A

defined('BASEPATH') OR exit('No direct script access allowed');

class ConA extends CI_Controller
{
function __construct()
{
    parent::__construct();
    $this->load->model('MAdmin');
}

public function user()
{
   $data = array (
        'titlepage' => APP_TITLEPAGE,
        'titleapp' => 'User Management',            
        'listdept' => $this->MAdmin->get_dept(),
        'complete' => 'false',
        'contentpage' => 'admin/user');//This is the view directory. Will open user.php in myproject/application/views/admin

    $this->load->view('shared/master_app', $data);
}

Con B

defined('BASEPATH') OR exit('No direct script access allowed');

class ConB extends CI_Controller
{
function __construct()
{
    parent::__construct();
    $this->load->model('MAdmin');
}

public function user2()
{
   $data = array (
        'titlepage' => APP_TITLEPAGE,
        'titleapp' => 'User Management',            
        'listdept' => $this->MAdmin->get_dept(),
        'complete' => 'false',
        'contentpage' => 'admin/user');//This is the view directory. Will open user.php in myproject/application/views/admin

    $this->load->view('shared/master_app', $data);
}

shared/master_app in Views

<div class="wrapper wrapper-content"><?php $this->load->view($contentpage); ?></div>

$config

$config['base_url']= "http://".$_SERVER['HTTP_HOST'].str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);

.htaccess in myproject/

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /myproject
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /myproject/index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
ErrorDocument 404 /index.php
</IfModule>

.htaccess in myproject/application

<IfModule authz_core_module>Require all denied</IfModule>
<IfModule !authz_core_module>Deny from all</IfModule>

Note:

In offline mode (Localhost) everything is run well
the URL in the address bar after a redirect from the link is the same (except the naming).

You Should Check this. codeigniter.com/user_guide/general/styleguide.html — ankit suthar
Not an expert but I am facing problem in the beginning when I start Codeigniter, in local my all URL is running ok but on the server that create problems and didn't load. So I found that I didn't follow the naming convention of CI. So You should check that first. — ankit suthar
what is the URL? Please add the access URL in your question. — Nishant Nair
It seem my new controller is not registered. I solve my problem by merge the controller. — Shota

If your localhost working well, The main cause of an issue is controller name which is ConA or ConB . Classes name start from Capital keyword. Please rename the Controller class and save the file as Cona.php . Maybe it works. Sometimes this issue creates a lot of bugs. First, try with this. Also Your URLs should be all lowercase letters. You can write anchor tag like as , e.g. :

<a href="<?php print base_url('conb/user2'); ?>">TEST2</a>
