I have Rails 3.2.3 with Apache and Passenger.
I have a project working in development mode.
When I switch the project to production mode (Passenger standard)
it gives me an HTTP Error 500:
We're sorry, but something went wrong.
This happens even with WEBrick.
Can somebody help me?
Edit:
My production environment file: http://pastebin.com/ZAudSzkc
Make sure you have ran $ bundle install. If this doesn't succeed, go to your production environment and connect to your server using ssh and $ tail -f log/production.log in your current production app.
This will generate an output which might show an error.
If this doesn't show an error in the log/ directory do $ ls -la if there are any passenger.error files open the latest and check for errors there.
Hope this helped you out!
In addition to log/production.log, you should also look at the web server error log, typically /var/log/apache2/error.log or /var/log/nginx/error.log. Some errors are written there instead. More information can be found in the Troubleshooting section of the Passenger manual:
