CI not called when using mod_rewrite with PHP5 running as cgi

can you try this .htaccess rule and let me know the results.

Code:

RewriteCond $1 !^(index\.php|images|robots\.txt|favicon\.ico)
RewriteRule ^(.*)$ /index.php?$1 [L]

This code is to skip the index.php from your urls. once you do this try to access pages/aboutus.
