Thanx Aken for your quick reply, but I already tried these things, these are not working in my case. I am new to CI please help me. my .htaccess file is like below

Code:

RewriteBase /ci/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [NC,L,QSA]
