Not a lot of information here, but it looks like you have an option under
[[Wunderground]] in weewx.conf that should not be there. Something like
[StdRESTful]
...
[[Wunderground]]
enable = true
station = KMDSOMETHING
password = MYPASSWORD
fields = something...
The highlighted option should not be there. There is no "fields" option for
the Wunderground uploader.
