It says exception notifier isn’t loaded. You will have to work from there to find out why: - If it’s a gem, you might not have included it in your config.gem section - If it’s a plugin, you might not have installed it into the vendor/plugins directory - … Best regards Peter De Berdt ---

I have tried both. Made sure the plugin is installed and the gem exception\_notification (2.3.3.0) is installed and it's in my enviornment.rb file as configm.gem "exception\_notification" I followed to documentation to the T. It's on rails 2.3.5.
