Ruby on Rails application could not be started
The application has exited during startup (i.e. during the evaluation of config/environment.rb). The error message may have been written to the web server's log file. Please check the web server's log file (i.e. not the (Rails) application's log file) to find out why the application exited.
If that doesn't help, then please use the backtrace below to debug the problem.
