Redmine

I recently upgraded to Redmine 0.8.0 on a Dreamhost shared server by following the instructions on RedmineUpgrade. Everything went smoothly except that now the stylesheets are no longer applied. I am getting a lot of messages like the following in my production.log file (also get similar errors for javascript files):

I tried uncommenting and updating the "config.action_controller.asset_host" property in config/environments/production.rb with no luck. Dreamhost recently upgraded all of their servers to Rails 2.2.2, but I don't think this should be the problem since rails is frozen into the vendor directory. The environment.rb file still specifies RAILS_GEM_VERSION as 2.1.2
