MSofficekey plugin not working with ocsng server 2.2

hi,

I'm running ocsng for unix 2.2 running on debian 8

I've followed the install description found on

http://wiki.ocsinventory-ng.org/index.php?title=Plugins:MSofficeKey

and

http://wiki.ocsinventory-ng.org/index.php?title=Plugins:ManageMSofficeKey

and watched the yt video

https://www.youtube.com/watch?v=VP4xpGX8caA

when I try to execute the php script

/usr/share/ocsinventory-reports/ocsreports/plugins/computer_detail/cd_officepack/cd_officepack.php

I get the following error in apache logs

PHP Fatal error:  Call to undefined function print_item_header() in /usr/share/ocsinventory-reports/ocsreports/plugins/computer_detail/cd_officepack/cd_officepack.php on line 10

line 10 in this script is the following

  print_item_header("Gestionnaire des licences Microsoft Office");

further I don't know where to find the office key in the ocs web gui, in ocsng 2.1 I was able to set the pages for the super administrator, this I can't find within 2.2 .. (all ms_xxx pages are missing)

anybody knows what to do, or if this plugin still works with 2.2?
