uninitialized constant ApplicationController::Mailer

353 Views Asked by At

When I run my rails application in development mode it runs fine. When I run it in production mode, it doesn't start. Instead it gives me: uninitialized constant ApplicationController::Mailer. This application has been upgraded from a rails 2 application, so is there anything I could be missing or any other ideas why it wouldn't be working?
