When opening the host status page (https://foreman.example.com/hosts/host1.example.com), it buggers out reporting

NoMethodError

This method is both called & defined from https://github.com/theforeman/foreman_bootdisk/blob/master/app/helpers/concerns/foreman_bootdisk/hosts_helper_ext.rb

Removing the Salt plugin resolves the problem, reinstalling it reintroduces it.
Apparently the Salt plugin attempts to do something to the hosts view which breaks the concern?
