    # Removes access to the system folder by users
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php/$1 [L]

what's the problem with the subdomain why this is not working

I have a Codeigniter on my sub-domain and it works fine. I mean the Codeigniter folder I have on my host server is working and my admin is working fine too.

So the question is what are you doing? I'm not sure why you changing your htaccess file when you don't necessary need to do that in the first place.

The htaccess file should be on the domain root not in the Codeigniter folder. Do you understand what I am talking about.

I have upload the htaccess file in main root folder but still get same error
actually when any page open the url would be http://oes.techpawer.com/site/developers but if i add the index.php before site/developers than it works perfectly fine but i don't want index.php http://oes.techpawer.com/index.php/site/developers

actually when any page open the url would be but if i add the index.php before site/developers than it works perfectly fine but i don't want index.php.

Regardless you still need a index.php file in that developer folder. I don't understand why you don't want it how can you access the admin section?
