No input file specified and htaccess

I faced the same problem andI found the solution in this link:

Fixing No input file specified issue

Basicly I put the .htaccess in the same directory as my CI project and the .htaccess should look like this:

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

In the config.php file (in my case ci/application/config/config.php - Depends of your directory organization)
you should set:

$config['base_url']='http://www.YOUR_PROJECT_NAME_GOES_HERE.COM/THE_DIRECTORY_OF_YOUR_CI_PROJECT_NAME';

$config['index_page'] = '';

and

$config['uri_protocol'] = 'AUTO';

Good Luck for everyone!
