Dan…
I will check the sd.json file, as I think you might be right about this. It seems that I had trouble connecting with my OSPi’s after previous updates. This resulted in my having to tweak the sd.json files with the correct port numbers (not 80 or 8080) for the interval program to be reachable. I will check out your method to see if this is fixed. Also, I’m unsure about the options.txt file and will check this as well. I clearly screwed up something on the previous upgrade (in trying to get the interval program and web app functioning).
Thanks again…
