"translation missing" in simple_captcha

captcha, ruby-on-rails-3.2

Solution

Add the following to your app's translation files (For example myapp/config/locales/en.yml):

en:
  simple_captcha:
    placeholder: "Enter the image value"
    label: "Enter the code in the box:"
    message:
      default: "Secret Code did not match with the Image"
      user: "The secret Image and code were different"

From the documentation here:

Problem

I have some sort of error that when you view this page, in the box where you enter captchas, it says "translation missing." I've looked around and noticed it may have something to do with i18n or flashes, but I am not sure, and nothing I've found regarding those two thus far has worked. Anyone able to lead me in the right direction?
