Q:

passenger issue with cloud66 deploy

when i deployed using cloud66 I got this:
First time this happened:
We're sorry, but something went wrong.
We've been notified about this issue and we'll take a look at it shortly.
The Phusion Passenger application server encountered an error while starting your web application. Because you are running this web application in staging or production mode, the details of the error have been omitted from this web page for security reasons.
Please read the web server error log to find the details of the error. If you don't know where the web server error log is, read the troubleshooting documentation below.
Alternatively, you can turn on the "friendly error pages" feature (see below), which will make Phusion Passenger show many details about the error right in the browser.
Phusion Passenger troubleshooting documentation:
Nginx integration mode
Apache integration mode
Standalone mode
To turn on friendly error pages:
Nginx integration mode
Apache integration mode
Standalone mode: pass the --friendly-error-pages parameter to the passenger command.

A:

I had a look at your error log, and it seems your Passenger instance can't start due to an issue in your application:
nginx_error.log — Message from application: /var/deploy/inrtracker_production/web_head/releases/20150621153940/app/controllers/discuss_topics_controller.rb:87: syntax error, unexpected keyword_else, expecting keyword_end

Could you please take a look at those lines, and ensure the conditionals are closed?
