After rails 7 and javascript updates, the buttons to link your profile to github and/or gplus still worked but caused the update for other fields to fail. It appeared that the 'PUT' request on the form was being changed to a 'GET.' So I took out the buttons and tests.
Possibly something in the add_social_account_button(provider, options) method in application_helper.rb.
