Hi, i have got Silverstripe 3.0.1 on Debian 6.0 Squeeze and i can't change theme. I extracted theme to the silverstripe theme directory, i changed theme in _config.php, i changed it in silverstripe settings, but it still can't load css. I tried to change mask of assets to 777, i tried ?flush=1 and ?flush=all but it still doesn't work. All ends with a white page with standard text. Silverstripe becomes very slowly in that moment.
