Live comments on Hangouts (PC)

  

 

   Not sure how it happened, but the chat box (the one the viewers see) does not show up in any of my live streams

If anyone knows how to re-enable it, I would be very appreciative. The directions on the youtube site are not clear to me. I did try looking this up before hand, but no joy. I think it is Google plus integration that is throwing me, but I am not certain.  I know this is not Software development type of an issue, but had no clue where else to put it.
