I recently had to reload my website at a new server and am having issue getting the widgets on right hand column to display properly. The top bar between each widget does not extend fully across. I thought there used to be a place in the Graphene Theme Custom Panel to adust this, I do see how to fix it? See my website Daltonskygazer to see issue I am having.
I was finally able to find the issue. I had to disable infinite scroll. Once infinite scroll was disabled the blocks around the widget area correctly displayed all the way across the width of the widget area.
