explorer view not available after upgrade

I had this configured before the upgrade so I had two panes, in the left, I saw the files on my desktop, on the right, I saw files on server.

I did check it correctly to use explorer view when I upgraded. But I only see server files on right AND on left.

how do fix I that? (I did restart computer, still displays wrong)

What you describe IS explorer view. You may be looking for commander view.
