Not sure if this will be of help but if you happen to have this line in your application.html.erb <%= stylesheet_pack_tag ‘application’, media: ‘all’, ‘data-turbolinks-track’: ‘reload’ %>
you should try removing it as this is how I fixed it

I have used this one in the past, pretty cool https://github.com/froala/wysiwyg-rails and also https://github.com/summernote/summernote-rails
