Added info, when I access the site the following message is displayed;
Web application could not be started
Web application could not be started by the Phusion Passenger application server.
Please read the Passenger log file (search for the Error ID) to find the details of the error.
You can also get a detailed report to appear directly on this page, but for security reasons it is only provided if Phusion Passenger is run with environment set to development and/or with the friendly error pages option set to on.
For more information about configuring environment and friendly error pages, see:
•Nginx integration mode
•Apache integration mode
