This afternoon I get enough courage to upgrade my Cumulus setup from 1.9.2. build 1028 to 1032, unfortunately with catastrophic results; the b1032 start, apparently download the latest data available from the data logger and updated the web sites, but I only get a "blank screen" all the time.
Since I was unable to watch the Cumulus screen, I killed the task using the Windows Task Manager and start over again, with identical results.
I just reinstalled the b1028 again and everything is running OK as before.
Attached a zip file with the diagnostics.
