It is possible that devise will release an update to make it compatible with the newer version of rails but until then. I highly recommend uninstalling rails 4.1 and installing rails 3.2 which is what they use on the videos. I had the same issue like you. From what I have read in other forum post they are working on newer videos that show you how to use rails 4. As a matter of fact not to long ago they updated the Ruby on Rails track and you can switch to the newer track however it does not include the project you are working on now.

163 PointsWhat I'm going to have to do is to downgrade my version. However I emailed treehouse support and they apologised for confusion with the old tutorials and they said they are planning on updating everything so that it will work with rails 4.1.

163 PointsI have just outputted what first and last name actually equal to through a label, which it turns out nothing apparently! So what does this mean now, what have I done wrong? I am using 4.1.1 ruby, maybe it is something to do with the parameters maybe for the statuses_controller.rb?
