CodeIgniter 404 Page Not Found, but why?

I am using CodeIgniter for two applications (a public and an admin app). The important elements of the document structure are:

/admin
/admin/.htaccess
/admin/index.html
/application
/application/admin
/application/public
/system
.htaccess
index.php

The /admin/.htaccess file looks like this: 

DirectoryIndex index.php
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php/$1 [L,QSA]

The /admin/index.php has the following changes:

$system_folder = "../system";
$application_folder = "../application/admin"; (this line exists of course twice)

And the /application/admin/config/routes.php contains the following: 

$route['default_controller'] = "welcome";
$route['admin'] = 'welcome';

Welcome is my default controller.

When I call up the Domain/admin I get a 404 Page Not Found error. When I call up the Domain/admin/welcome everything works fine. In the debug logs I get the following error message: 

DEBUG - 2010-09-20 16:27:34 --> Config Class Initialized
DEBUG - 2010-09-20 16:27:34 --> Hooks Class Initialized
DEBUG - 2010-09-20 16:27:34 --> URI Class Initialized
ERROR - 2010-09-20 16:27:34 --> 404 Page Not Found --> admin

Weirdly enough this setup works perfectly on my local MAMP installation (with the localdomain/admin/), but when I publish and test it on the "live" server, I just get 404 errors.

Any ideas? What am I doing wrong? Thanks C.

If you installed new Codeigniter, please check if you added .htaccess file on root directory. If you didn't add it yet, please add it. You can put default content it the .htaccess file like below.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
#'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]

#When your application folder isn't in the system folder
#This snippet prevents user access to the application folder
#Submitted by: Fabdrol
#Rename 'application' to your applications folder name.
RewriteCond %{REQUEST_URI} ^application.*
RewriteRule ^(.*)$ /index.php?/$1 [L]

#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn't true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.

Modify apache config file as mentioned below :

sudo nano /etc/apache2/apache2.conf

Goto line no 172 and change

<Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

to

<Directory /var/www/>
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>

and then finally

sudo systemctl restart apache2

If your application is in sub-folder then the Folder name in directory and URL must be same (case-sensitive).

It happens cause of multiple reasons but the answer missing above there's the "className" while extending your controller.

Make sure your class name is the same as your controller name is your controllers. e.g., If your controller name is Settings.php, you must extend the controller like.

class Settings extends CI_Controller
{
// some actions like...
     public function __construct(){
     // and so and so...
     }
}
