Plugins

When i select any host from Compute Resources -> 'provider' -> Virtual Machine -> 'vm' and click host, the web interface produces this error:

Oops, we're sorry but something went wrong undefined method `host_expiry_warning_message' for #<ActionView::Base:0x00000001aa8290>

Also when clicking on a host in "All Hosts" I do not see any expiry information in any tab.

I'm using the ubuntu package for the plugin from the foreman repos:

@ruby-foreman-expire-hosts:
Installed: 8.1.0-1
Candidate: 8.1.0-1
Version table: *** 8.1.0-1 500
500 http://deb.theforeman.org plugins/3.6 amd64 Packages
100 /var/lib/dpkg/status
8.0.0-1 500
500 http://deb.theforeman.org plugins/3.6 amd64 Packages@

Any help would be much appreciated!
