Question

I have searched all day in this forum and found same problems like mine,tried all the answers but just wont work.

In my locahost, everthing is fine, but later when I decided to upload it to a live webserver, it starts showing

The server encountered an internal error or misconfiguration and was
unable to complete your request.

Please contact the server administrator,
[e-mail] and inform them of the time
the error occurred, and anything you might have done that may have
caused the error.

More information about this error may be available in the server error
log.

Additionally, a 500 Internal Server Error error was encountered while
trying to use an ErrorDocument to handle the request.

In my error log I’ve seen this:

[Tue Jan 29 22:05:53 2013] [error] [client 112.198.77.50] File does not exist: /home/cnnpa/crs/404.shtml
[Tue Jan 29 22:05:53 2013] [error] [client 112.198.77.50] File does not exist: /home/cnnpa/crs/crimeindex

I think this has something to do with .htaccess and mod_rewrite based on reading similar questions. When I remove .htaccess it seems to work, but I dont want this solution because at the first place I used .htaccess for the purpose of having a cleaner URL’s(by removing the index.php).

Here is my current .htaccess

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /crs/

    #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.
    # Submitted by: ElliotHaughin

    ErrorDocument 404 /index.php
</IfModule>

in my config.php

$config['base_url'] = 'http://reportingsystem.cnnpa.com/';
$config['index_page'] = '';
$config['uri_protocol'] = 'AUTO';

RewriteBase /crs/

My first suspect will be the RewriteBase value in your htaccess file.

Looking at your config.php it seems you are serving the application out from the DocumentRoot. if that is the case the RewriteBase should be written as below.

RewriteBase /
