Redmine

Hey guys... I'm trying to install a new theme and a plugin, but they are not appearing in the administration panel, where they should be.

My theme folder is inside /var/www/redmine-2.1.4/public/themes and has the correct path to css: /var/www/redmine-2.1.4/public/themes/a1/stylesheets/application.css

For the plugin, i copied the folder to /var/www/redmine-2.1.4/plugins and ran the install command in the redmine root, and restarted apache in the end: http://pastie.org/8063823

Am i doing anything wrong?

The information pannel shows that the plugins directory is not writable. These are the permissions at the moment: http://pastie.org/8063897

Environment:
Redmine version 2.1.4.stable
Ruby version 1.8.7 (i686-linux)
Rails version 3.2.8
Environment production
Database adapter MySQL
Redmine plugins:
no plugin installed
