Omniauth devise Authentication failure! csrf_detected:

I got the Authentication failure! csrf_detected: so that I couldn't login with omniauth.

I followed this tutorial

and I found similar issue here,

But there are no luck for my problem till now.

Any idea for fixing the error ? Thanks

It looks like you also asked this question on the Omniauth Facebook Github Repo. It didn't look like there was a solid answer there either.

@dmcbrayer did suggest changing your initializer to look like:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :facebook, ENV['FACEBOOK_KEY'], ENV['FACEBOOK_SECRET'],
   :scope => 'email',
   :info_fields => 'email'
end

This was due to an API change on facebook side which required you to explicitly ask for info_fields.

The maintainer @mkdynamic also wanted you to verify whether it was fixed in a newer version (3.0.0 at the time).
