htaccess problem

RewriteEngine On
RewriteBase /home
RewriteRule ^()$ index.php [NC,L]
Rewritecond %{REQUEST_URI} !(^/?.*\..*$) [NC]
RewriteRule (.*)$ $1.php [NC开发者_StackOverflow社区]

I get a css problem (blank) when I visit http://dot.com/home/index.php/

Turning on the logging can help. Just add these directives to the .htaccess file:

RewriteLog "/foo/bar.log" 
RewriteLogLevel 3

Make sure to turn them off when done, as they can slow down your server.
