HELP for usign this plugin “Network Posts Extended”

I started a tutorial here:
https://agaveplugins.com/tutorials/plugins/multisite/network-posts-extended/
but it’s still a work in progress. Right now if you are using version 7.2.7 roll back to version 7.2.6 or upgrade to 7.2.8 which will be version 7.2.6 again until I get it sorted out.
