CodeIgniter htaccess and URL rewrite issues

There are 3 steps to remove index.php.

1. Make below changes in application/config.php file

   $config['base_url'] = 'http://'.$_SERVER['SERVER_NAME'].'/Your Ci folder_name';
   $config['index_page'] = '';
   $config['uri_protocol'] = 'AUTO';
   

2. Make .htaccess file in your root directory using below code

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

3. Enable the rewrite engine (if not already enabled)

   i. First, initiate it with the following command:

   a2enmod rewrite
   

   ii. Edit the file /etc/apache2/sites-enabled/000-default

   Change all AllowOverride None to AllowOverride All.

   Note: In latest version you need to change in /etc/apache2/apache2.conf file

   iii. Restart your server with the following command:

   sudo /etc/init.d/apache2 restart
