Hi. I am using rails 2.3.5 I just installed exception\_notification 2.3.3.0 using ‘sudo gem install exception\_notification’ I have add config.gem “exception\_notification” in environment.rb and ‘include ExceptionNotification::Notifiable’ in application\_controller.rb Now I am trying it out in development environment. It seems to catch my exception but fails to send email, here is the stacktrace found in the log: undefined method `find_template' for #
