Hello,

I upgraded from 5.15 to 5.17 earlier today, I copied off the device settings and sensor data first as instructions, and upgraded successfully to the new version.

Once upgraded, I copied back the settings & sensor data to the device.

I then went straight to the web browser to have a look at the pretty new web interface - and behold, it didn't ask me for the password that I had configured previous to the upgrade..
After reconfiguring the password, it worked as expected..

Does the settings file include the Admin/Guest passwords for the webserver? Perhaps they didn't restore correctly?

I hope this is helpful.

Many thanks,
Rob
