If "Adafruit-DHT" is not installed correctely according the Wiki, but the corresponding section in webradio.conf is "activated" like:

# IMPORTANT: give the GPIO not the Pin-No (Pin3 is GPIO2 for example)

# GPIO_TEMP: Where is the DHT11-Sensor connected with the I2C Line to the Pi ? Use GPIO! (Pin3, is GPIO2)
# delay_tempmeasurement : How often (in Seconds) should the Temperature-Label updated ? in Seconds! 3 minutes == 180sec.
delay_tempmeasurement = 180

The lib is failed to load, during startup, but is tried to use. This leads to an error-entry in webradio.log:

2019-02-10 10:10:15,713 - ERROR - - excepthook - Uncaught exception
Traceback (most recent call last):
File "/opt/webradio/lib/", line 305, in run
File "/opt/webradio/lib/", line 168, in startup_temperature_sensing
humidity, temperature = Adafruit_DHT.read_retry(tempsensor, GPIO_TEMP)
NameError: global name 'Adafruit_DHT' is not defined

The root-cause is the missing DHT11 Lib, but this should be recognized anyway and avoided.
"" has to be adjusted (import-section) in order to catch this situation properly.
Also this "warning" should be present in the logs as well, for debugging purposes.
