symfony2:You have requested a non-existent parameter "secret"

Question

After installing and configured sonata admin. I have got following error in my framework. Please help..

You have requested a non-existent parameter "secret".

Answer 1

Be sure to import your parameters.yml file at the top of you config.yml file

imports:
    - { resource: parameters.yml }

Answer 2

In your parameters.yml, you must have an attribute "secret", because in your config.yml you have a reference to "secret" with this line : secret: %secret%
