Answer 1

Maybe comment this two lines

config/environments/development.rb:  

# config.active_record.mass_assignment_sanitizer = :strict
# config.active_record.auto_explain_threshold_in_seconds = 0.5

Answer 2

You're probably setting some config.active_record settings somewhere in your config folder (development.rb, test.rb, etc). You'll want to comment out these settings since you're not using ActiveRecord.

You can do something like grep -r active_record config/ in your project folder to find files referencing active_record.

Update: Make sure you have removed the require 'rails/all' line from config/application.rb as well. The new require lines you added are supposed to replace that line. Otherwise, rails/all still loads ActiveRecord.
