Question

I suspect this may be a webserver configuration change that has taken place, and my hosting provider hasn’t told anyone, but anyway…

I have a Codeigniter instance set up with the following directory structure:

/root
   /codeigniter
        /app
        /sys
   /www
        /sandbox
            /ci
                /js
                /css
                /img
                .htaccess
                index.php

Therefore in index.php, I have the following variables:

$application_folder = '../../../codeigniter/app';
$system_path = '../../../codeigniter/sys';

These are relative definitions due to it being a shared hosting provider, however it does appear to be working that way so I don’t think this is the issue (in WAMP i have those folder paths explicitly defined, e.g. c:/wamp/ci/application)

In config.php, I have the following variables set:

$config['base_url'] = 'http://******.co.uk/sandbox/ci/';
...
$config['index_page'] = '';
...
$config['uri_protocol'] = 'AUTO';

and my .htaccess file in www/sandbox/ci is set like so:

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

Up until a few days ago, this all worked fine, however, I replaced a fair few files just before Christmas, and may have accidentally overwritten something without realising it. This setup works fine on my WAMP server, but fails on my live server If I attempt to access any function in any controller that isn’t the one defined in routes.php.

My routes.php looks like this:

$route['default_controller'] = "home_controller";
$route['404_override'] = '';

home_controller appears fine, however if I attempt to do something like login (which is processed via a form POST to auth_controller/login), it fails with 404. I do not have any additional functions in home_controller.

I get nothing interesting from setting the logging threshold to 4, and ChromePHP just suggests that it cannot find a path to the controllers.

mod_rewrite seems to be working, because if I add anything plaintext to the .htaccess file, I get a server error 500, and furthermore the index.php rewrite is working. I also have rewrite_short_tags set to TRUE.

I have tried all of the uri_protocol types in the config.php, and none seem to make any difference, so I feel like if it is something i’ve done, i’m either missing something from routes.php, or something missing from my .htaccess.

Any thoughts would be appreciated. Like I said, this entire setup works on my WAMP server without issue.

I think the problem is in your htaccess. Try this htaccess for a moment..

<IfModule mod_rewrite.c>

RewriteEngine On

# Set the rewritebase to your CI installation folder
RewriteBase /sandbox/ci/


# Send everything to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

</IfModule> 

I hope this helps you out.
