I love this gem and have successfully used it for several years. For some reason, I just started getting this error:
ActionController::UnpermittedParameters in Admin::PostsController#create
I tried adding :_wysithml5_mode as a permitted param, but that did not work.
I'm running:
activeadmin 1.0.0.pre2
Rails 4.2.4
Ruby 2.2.3
Thanks in advance.
