Hello,
TL;DR - your plugin might be incompatible with develop branch soon, this
explains how to fix it.
Dominic's patch which moves from the protected_attributes gem to
strong parameters in controller concerns is RTM. Some plugins will need
to be updated in order to remain compatibility with develop core branch:
https://github.com/theforeman/foreman/pull/3659
If there are no objections, I will merge the patch by end of the week.
An example of such a change in a plugin is discovery:
https://github.com/theforeman/foreman_discovery/pull/285
