I have installed, uninstalled etc Post Grid Pro. I would like to use L-R layout in flat for the Our Stories Post Grid. When I click on eother the layout or grid selection, it goes to the correct option, but then I get the little wheel of death....it has been doing this for days...it is doing it for all of the post grids I have ceated...but I only wish to edit Our Stories.
Welcome to our forum.
Not sure what you mean by L-R layout, you probably looking for HalfThumbLeft or HalfThumbRight layouts
please see the demo here
you will need to set grid item width 100% or 1 column
and then import the above layout and select the layout.
