Upgrading Rails broke my site
My web host, Dreamhost, recently upgraded Rails to 2.1.1. This broke my Recipes site.
It's fixed now, but unfortunately it was down for a few days since I didn't notice right away.
The way I got it working again was surprisingly easy:
I created a new Rails application from scratch ("rails recipes"), I copied my app directory, config/database.yml, config/routes.rb, and public directory over, and that was about it. The app just worked.
I should go make some Cookies to celebrate.
