htaccess URL rewriting

[jayar]

I am using my framework which ussually have these lines on my .htaccess file

RewriteEngine on
RewriteBase /
RewriteCond %{QUERY_STRING} !mod= [NC]
RewriteRule ^([^/]+)$ /index.php?mod=$1 [L]

Im not sure why it is not working on the server.

Basically this entry is hiding the GET parameter "mod" and pass it to index.php
www.domain.com/page is actually www.domain.com/index.php?mod=page

This is surely working for other servers like hostgator, gandi and OVH.

BTW: this is my page http://jayar.x10hosting.com/

Error_logs

[Wed Jan 13 23:47:19 2010] [error] [client 67.227.143.212] File does not exist: /home/jayar/public_html/login

The rewriting is not working then right?

If you're referring to the 500 response, there might be something else misconfigured in your .htaccess. Post the rest of it.
