Using htaccess to remove codeigniter index.php in a subdirectory - .htaccess

Question

I'm trying to remove the index.php from my CI urls, but having followed the instructions it doesn't seem to be working.
I have a codeigniter installation running in a subdirectory. There is a default controller set in the routes config called main, and another controller called 'create'. The default runs fine, but going to /create returns a 324 error saying No Data Received. My htaccess looks like this:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
ErrorDocument 404 /index.php
</IfModule>

Answer 1

This should be enough:
<IfModule mod_rewrite.c>
RewriteEngine On
#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
#This last condition enables access to the images and css folders, and the robots.txt file
RewriteCond $1 !^(index\.php|public|images|robots\.txt|css)
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

Answer 2

This is what I use. My CodeIgniter also runs in a subdir.
RewriteEngine on
RewriteCond $1 !^(index\.php|images|swf|uploads|js|css|robots\.txt)
RewriteRule ^(.*)$ /ci/index.php/$1 [L]

Answer 3

.htaccess add:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]
Go into application/config/config.php and clear the index page config value:
// Old
$config['index_page'] = "index.php";
// New
$config['index_page'] = "";
Solved My problem hope others too... :)

Sometimes you need to enable it the rewrite module, run "apache2 enable module rewrite":
sudo a2enmod rewrite
You need to restart the webserver to apply the changes:
sudo service apache2 restart
