My dad recently upgraded weewx for his Davis Vantage Pro2 to version 5.2
and it's not fully working any more. He's using the Belchertown skin on
Ubuntu (I think). Here is a section from the logs:

Seemingly it's an error related to the sunshine hours variable that I added
using this: https://github.com/Jterrettaz/sunduration. I'm in a different
country to my dad so it's a bit difficult for me to debug it, so I thought
I'd see if anyone can suggest something obvious that would be causing it.
It didn't seem like any of the main files in /etc/weewx/ or
/usr/share/weewx/ had been modified recently by the upgrade but I could
have missed it. He chose the option to keep the existing weewx.conf when
prompted, so I've already had him make the change to "schema =
weewx.schemas.wview_extended.schema"
in that in case that's necessary.
