Is something missing for cookies or session settings or any changes required for devise?

I am facing different issue as well Rails 4 upgrade JSON::ParseError for old sessions

Ruby on Rails TypeError

But no luck I had changed secret token.

Answer 1

It seem to be a checksum verification error. And in the callstack it comes just after CookieStore middleware. I'd try the following:

1. Empty cookies and cache in my web browser
2. If using server side cookie store: empty its storage (ex: empty the sessions database table when using activerecord-session_store)
3. Clean the content of my_app/tmp directory with rake tmp:clear

Answer 2

i had the same issue when i upgraded from Rails 3.2.16 to Rails 4.2.0 and it was assets problem try do the following:

bundle exec rake assets:clean
bundle exec rake assets:precompile
