Problem: Inviting your friends to ‘like’ your facebook page.
Click Suggest to friends
and now you get to select people. BUT… you can’t choose people with a kind of grayed out profile image. There can be several reasons for this. Maybe they already have liked your page or perhaps they have settings that prevent others from inviting them to like pages.
Those with a green circle can be invited. Those with red cannot.
N.B. I have blurred the names.
