I tried to remove index.php from url. I tried more links from linkden but have not worked. I tried following.
1.add .htaccess file with following data,
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]
2.changed in config.php $config['index_page'] = ''
;
3.activate mod_rewrite
.
But still not working.
