I really cannot get it working. I’ve added the ID of the g+ page, and my g+ account which is the owner of the page.

It looks like this:

One Google account
One G+ profile (Me)
One G+ page (run by Me for the Page)
A Youtube account with a channel for Me
Another channel run with that account for Page

What ID should be placed? In the other hand the whole G+ / Youtube / profile / pages are very confusing.
