NameError in Devise/sessionsController#new

[NazarHussain]

I created a sample application.
Added devise in it, it works fine.

Then added cancan gem into it.

Created an ability class. define some permissions.

Then added line

load_and_authorize_resource

to the Application Controller, after that when i go to the page
http://0.0.0.0:3000/users/sign_in it gave the following error,

NameError in Devise/sessionsController#new
uninitialized constant Session
Rails.root: /home/nazar/rails_projects/sample_can

Please help me, i can not solve this issue.
