If other images are being generated, but only the dayhumidity.png image is
missing, the problem must be in the skin.conf file. If you did a Debian
install, it will be located in /etc/weewx/skins/Standard/skin.conf
The relevant section should look something like this:
...
[[[daytempchill]]]
[[[[windchill]]]]
[[[[heatindex]]]]
[[[dayhumidity]]]
[[[[outHumidity]]]]
[[[dayrain]]]
# Make sure the y-axis increment is at least 0.02 for the rain
plot
yscale = None, None, 0.02
plot_type = bar
[[[[rain]]]]
aggregate_type = sum
aggregate_interval = 3600
label = Rain (hourly total)
...
