Rewrite In Lighttpd 1.5

i had following rewrite (for wordpress multi user ) and it was working with lighttpd 1.4.x but i dont know its not working in 1.5

Quote:

$HTTP["host"] == "blogs.domain.com" {
url.redirect = ("^/(.*)" => "http://%1/$1")
url.rewrite-once = ("^/(.*)?/?files/(.*)" =>
"wp-content/blogs.php?file=$2", "^/(wp-.*)$" => "$1",
"^/([_0-9a-zA-Z-]+/)?(wp-.*)" => "$2", "^/([_0-9a-zA-Z-]+/)?(.*.php)$" => "$2", "." => "index.php")
}

and its showing following error

Quote:

mod_rewrite.c.293: (error) url.rewrite contains a regex for '/' which
leads to a URI without a leading slash: index.php
