Why I get 404.php error in the in the js and css folder

I get this error message depending on the page you visit:


When I go to the link with Chrome it says:

This webpage has a redirect loop

What I have done wrong. Here’s my code:

Options +FollowSymLinks

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^(.+)$ url.php?url=$1 [L]

I use it to write beautiful URL like www.mywebsite.com/myName

Thank you,

Never mind. I fixed it with Google optimization tool.
