Problem with rights module url

Hi Guys, I am working on a test site. I have installed rights module. I can reach it’s assignment menu, but it shows following error when clicking on permission , roles, task, operations.

Error 404

Unable to resolve the request "rights/authItem/assign".

Here is my htaccess file rule.

RewriteEngine on

if a directory or a file exists, use it directly

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

otherwise forward it to index.php

RewriteRule . index.php

I have following url format for my site.

http://www.subdomain.maindomain.com/rights/authItem/operations

Testing server is linux machine. It’s working on local system. I have search on web for all possible solutions but nothing work.

Please help.

Regards

Sorry Guys, found solution, I removed following line from my url-manager component setting in /protected/config/main.php

‘caseSensitive’=>false

and everything worked.
