Rails App Error: Premature end of script headers

Question

My setup: Ubuntu 12.04 LTS, Apache, Phusion Passenger, latest Ruby and Rails.

When I visit my website, I get a 500 Internal Server Error. Error Logfiles: Premature end of script headers

Does somebody know how to solve that problem?

Answer 1

Just posting here in case other people have the same problem as I did.

I followed the Rails tutorial and part of that tutorial was making sure the secret_token was generated dynamically (listing 3.2 in the link) as a .secret file in the application root.

The problem was that the application somehow didn't write a token to the file, so I took the value from my development .secret, modified it, and saved it on the server. That made my application work in production.

If you have a database configured for production in your config/database.yml that doesn't exist on the server as you mentioned in the comments, that could be the source of your issue since it's failing to establish a database connection.

Remove that connection from your config/database.yml and restart your app.
