/*****************************ISSUE: 3****************************************/

ArgumentError

wrong number of arguments (3 for 1)

Parameters:

None

Show session dump
Show env dump

Response

Headers:

None

Solution:

Run bundle show and check version of omniauth gem. May be while upgrading rails you updatedomniauth as well.

Version 1.* of omniauth requires separate gem omniauth-twitter for twitter authentication. As you don't have it in your Gemfile it tries to load as middleware Twitter class from twitter gem that would cause similar error.

To avoid issues like that in the future consider using "~> 0.2.6" for gems versioning instead of ">= 0.2.6". It protects you from unexpected major releases of gems you're using.
