Codeigniter -> getting 404 error. Simple routes not working - php

Question

I am an asp.net guy and this is the first time I've dealt with PHP.
Anyhow, I've struggled to migrate an existing site to a new server.
This site is using codeigniter.
When I call http://mydomain/admin
I get a 404 error!
But if I call:
http://mydomain/index.php/admin
it works!
I have placed an .htaccess file on the root:
RewriteEngine on
RewriteCond $1 !^(index\.php|images|stylesheets|scripts|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]
I have set in the config.php:
$config['index_page'] = '';
My routes.php:
$route['default_controller'] = 'welcome';
$route['scaffolding_trigger'] = '';
I have no idea why it does not work. It must be something very simple I guess...
Thank you!

Answer 1

Did you look through this?:
http://codeigniter.com/wiki/mod_rewrite/
If not, try this one:
<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.

ErrorDocument 404 /index.php
</IfModule>
There used to be one from Jamie Rumbelow I used to use a bit, but it's not on his blog anymore... I'm used to nginx now though, so my favorite configuration won't work for you.

Answer 2

Your .htaccess file didn't work for me either. But it worked once I changed the rewrite rule to this :
RewriteRule ^(.*)$ index.php/$1 [L]
I just removed the slash at the beginning.

Answer 3

Try this:
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]

Answer 4

1º - Create an .htaccess file in the root you're CodeIgniter project.
2º - In the created .htaccess file put the code:
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]

Answer 5

try adding RewriteBase / in .htaccess

Answer 6

$default_controller = "home";
$language_alias = array('gr','fr');
$controller_exceptions = array('signup');
$route['default_controller'] = $default_controller;
$route["^(".implode('|', $language_alias).")/(".implode('|', $controller_exceptions).")(.*)"] = '$2';
$route["^(".implode('|', $language_alias).")?/(.*)"] = $default_controller.'/$2';
$route["^((?!\b".implode('\b|\b', $controller_exceptions)."\b).*)$"] = $default_controller.'/$1';
foreach($language_alias as $language)
$route[$language] = $default_controller.'/index';
$route['404_override'] = '';
