Hi,
I've got a weewx installation on a CentOS VM that's been running happily
for about a year. About a month ago, I realised that the 'forecast' wasn't
working, but have only now found the time to look into it.
The station used wunderground, so I head over there, login and then to to
the 'API keys' tab. I generate a new API, dump it to the clipboard, and
then put it into the weewx.conf ..
[Forecast]
data_binding = forecast_binding
[[OWM]]
api_key = INSERT_OWM_API_KEY_HERE
[[WWO]]
api_key = INSERT_WWO_API_KEY_HERE
[[WU]]
api_key = XXXXXXXXXXXXXXXXXXXXXXX
[[NWS]]
lid = "INSERT_LOCATION_ID_HERE (e.g., MAZ014)"
foid = "INSERT_FORECAST_OFFICE_ID_HERE (e.g., BOX)"
[[UKMO]]
api_key = // no longer used
location = 1234
I restart weewx and watch the logs.

So I think that maybe it has something to do with the fact that my default
skin is 'john':
[[StandardReport]]
# See the customizing guide to change the units, plot types and line
# colors, modify the fonts, display additional sensor data, and
other
# customizations. Many of those changes can be made here by
overriding
# parameters, or by modifying templates within the skin itself.
# The StandardReport uses the 'Standard' skin, which contains the
# images, templates and plots for the report.
skin = john
[[[Units]]]
[[[[Groups]]]]
group_altitude = foot
group_speed2 = mile_per_hour2
group_pressure = inHg
group_rain = mm
group_rainrate = mm_per_hour
group_temperature = degree_C
group_degree_day = degree_C_day
group_speed = mile_per_hour
[[[Extras]]]
[[[[forecast_strip_settings]]]]
source = WU
num_days = 3
I can state categorically, however, that none of the files was changed, and
indeed hadn't been for months. So I still think it's something to do with
the api key. But since I've generated a new one, I'm a bit lost.
