Thank you very much it is now working, it had nothing to do with what you had written, I had an error in my config.js, I had inserted showSunriseSunset = true; and that obviously was completely wrong. I removed that line and bingo all is well. Thank you again.

Thanks but no joy, I added the following to the MMM.darkskyforecast.js

var summary;
if (this.config.concise) {
summary = this.weatherData.hourly ? this.weatherData.hourly.summary : this.weatherData.currently.summary;
} else {
summary = (this.weatherData.minutely ? this.weatherData.minutely.summary : this.weatherData.currently.summary + “.”) + " " +
(this.weatherData.hourly ? this.weatherData.hourly.summary + " " : “”) +
(this.weatherData.daily ? this.weatherData.daily.summary : “”) + " | " + "Sunrise: " + moment(new Date(this.weatherData.daily.data[0].sunriseTime * 1000)).format(“LT”) +
" | Sunset: " + moment(new Date(this.weatherData.daily.data[0].sunsetTime * 1000)).format(“LT”);
}

(leaving out the humidity and dew point in the example) now I get the black screen!

Thank you in advance for any assistance, as you can tell I am a noob.

Thank you in advance, has anyone configured the sunrise and sunset in the dark sky
forecast module? I have seen the question asked but cannot find an answer.
