.htaccess (again)

First of all I would like to thank Samboll for his help earlier today.

I have created a .htaccess for my blog on xxxx.com/vince/ as below and put this in this directory.

RewriteEngine On
RewriteBase /vince/
RewriteRule ^css/(.*\.css) vince/combine.php?type=css&files=$1
RewriteRule ^javascript/(.*\.js) vince/combine.php?type=javascript&files=$1

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /vince/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /vince/index.php [L]
</IfModule>
# END WordPress

Also in this directory I put the combine.php, see below.

Strange enough I still get the error “FAILED: Combine static CSS and JS files” when using the webpagetest.

Am I doing something wrong here ??
