Sub-theme

I’m trying to build a Sub-theme that derivate from bluemarine.
I'm running drupal 6 and using the default submarine theme which is included in drupal package.

I’ve created themes/bluemarine/theme-name directory with theme-name.info and style.css file.
The theme-name with all its all sub content rights are 755 and owner is webuser.www-data.
The rights for sites/default/files are 775 owned by webuser.www-data.

Content of theme-name.info :
; $Id$

name = theme-name
description = Table-based multi-column theme with a Cartesian flavor.

version = 1.0

core = 6.x

base theme = bluemarine

stylesheets[all][] = style.css

Content of style.css
#sidebar-left {
color:red;
background-color:yellow;
}

In admin/build/themes I’ve enabled bluemarine, theme-name and I’ve choosen theme-name as the default one. I’ve also cleared cached data under Home » Administer » Site configuration.

Following theme system documentation this is all I need.
When I browse website I should see exact copy of bluemarine theme with red fonts but all a see is attached picture “no_teme.png”.

Do I miss any settings?
