I was able to resolve my problem by:
1) In the file OSPi/data/sd.json, replace
“nbrd”: 2
by
“nbrd”: 1
2) Login and change the number of extension boards back to 1 in the options (I do have one extension board)
3) In the process I lost the stations names, so I had to re-enter them
My system now seems to be mostly normal, except for an error when I try to use the weather-based water level plugin, for which the “status” box shows
Weather-base water level encountered error:
