Configuration.yml is not a valid YAML file and could not be loaded - error comes after editing smtp settings for email configuration

Hello all,

My redmine configuration is:
Ruby version 1.8.7 (i386-linux)
RubyGems version 1.3.7
Rack version 1.1.6
Rails version 2.3.14
Active Record version 2.3.14
Active Resource version 2.3.14
Action Mailer version 2.3.14
Active Support version 2.3.14
Application root /var/www/redmine-1.4.4
Environment production
Database adapter mysql
Database schema version 20120301153455

Operating system :CentOS 6.2

I change the SMTP settings in /var/www/redmine/config/configuration.yml file

==== SMTP server at using TLS (GMail) #
production:
email_delivery:
delivery_method: :smtp
smtp_settings:
tls: true
enable_starttls_auto: true
address: "smtp.gmail.com"
port: 587
domain: "smtp.gmail.com"
authentication: :plain
username: "username@gmail.com"
password: "password"

I save this file, then go to /var/www/redmine, run the following command-
#ruby script/server webrick -e production

I get the following error:
=> Booting WEBrick
=> Rails 2.3.14 application starting on http://0.0.0.0:3000
Your Redmine configuration file located at /var/www/redmine-1.4.4/config/configuration file is not a valid YAML file and could not be loaded.

when I try to open redmine in a browser window by typing the redmine server's IP address, I get "Web Application could not be started" error ( I have attached the page here). This error comes only when I restart the htttpd service. If I dont restart the service, I am able to open redmine in a browser window.

If I comment out the SMTP server settings in the configuration.yml file, I am able to run the #ruby script/server webrick -e production command with no errors and redmine runs fine.

Pls help as I am newbie to redmine and I have to configure email notification.
P.S: I am using gmail smtp settings for testing. If this works, then I need to configure an external mail server hosted on the web server service provider used by my company.

Any guidance will be greatly appreciated.

Regards,

Rajesh

In YAML, whitespace matters. You have to have leading spaces just like in the examples.

Hello Jan,

Thanks a lot for your help.

I opened the configuration.yml file, commented out the smtp settings under SMTP server at using TLS (GMAIL), then edited the smtp settings under #default configuration options for all environments. I changed the options as per my email server settings. Tested my redmine installation using ruby script/server command and restarted httpd service.

Now I am able to send email notification using the tracker tool.

Thanks for your help.
