CodeIgniter PHP Apache 500 Internal Server Error

Question

I did a project in CodeIgniter. It's working fine on my localhost, but giving "500 Internal Server Error" on the remote server. This is my .htaccess file content:

RewriteEngine On
RewriteBase /ezgov
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

Answer 1

Open httpd.conf generally located in Apache installation directory in windows

/apache/conf/httpd.conf

and

/etc/httpd/httpd.conf

in Unix based systems. httpd.conf is an Apache configuration file which stores various information about the server.

Search for the module mod_rewrite.so or (mod_rewrite.c in rare cases). mod_rewrite module is developed to rewrite the requested URLs on the fly. Most of the time you will find in commented state.

#LoadModule rewrite_module modules/mod_rewrite.*

Here # character represents that it is commented or disabled.

LoadModule rewrite_module modules/mod_rewrite.*

Remove # and restart the Apache Http Server using the command apache -k restart in windows or service httpd restart in unix systems. You also use XAMPP/Wamp UI to restart Apache in windows systems.

Next create .htaccess file in root directory where your CodeIgniter project is located and paste following code

# index file can be index.php, home.php, default.php etc.
DirectoryIndex index.php

# Rewrite engine
RewriteEngine On

# condition with escaping special chars
RewriteCond $1 !^(index\.php|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php/$1 [L,QSA]

Next Find CodeIgniter configuration file, generally located in it's configuration directory.

./application/config/config.php

Open the file and make $config['index_page'] value empty. which looks like this

/*
  |--------------------------------------------------------------------------
  | Index File
  |--------------------------------------------------------------------------
  |
  | Typically this will be your index.php file, unless you've renamed it to
  | something else. If you are using mod_rewrite to remove the page set this
  | variable so that it is blank.
  |
 */
$config['index_page'] = '';

Now the story is ended. Everything should work fine. You can find more information about httpd.config at Apache Module mod_rewrite. Hope this helps you. Thanks!!
