Hi, I have asked this question on github<https://github.com/rails/rails/issues/15175> . Senny answered me to set export SECRET_KEY_BASE =d1f4810e662acf46a33960e3aa5bd0 ************************ in your peoduction server. but I do not know how to set that. I am deploying in openshift. I also have access to SSH via putty. I have tried this command in SSH but it gives an error "Invalid identifer". Where should I run this command? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
