 Config looks good, could you have a look at your logs? See here for some troubleshootign info: https://forum.magicmirror.builders/topic/86/how-to-troubleshoot

 @MagicCrumps1 On the other hand, you api key seems to be invalid. (if the key in your post is indeed your key): { "response": { "version":"0.1", "termsofService":"http://www.wunderground.com/weather/api/d/terms.html", "features": { } , "error": { "type": "keynotfound" ,"description": "this key does not exist" } }

 @RedNax Still not working. Sorry, I should have included that I added a few extra keys to my personal api key thus making them invalid. Loading config … Loading module helpers … No helper found for module: alert. No helper found for module: clock. Initializing new module helper … No helper found for module: compliments. No helper found for module: currentweather. No helper found for module: MMM-WunderGround. Initializing new module helper … All module helpers loaded. Starting server op port 8080 … Server started … Connecting socket for: calendar Starting node helper for: calendar Connecting socket for: newsfeed Starting module: newsfeed Sockets connected & modules started … Launching application.

 That looks like everything did load up properly there. There’s a way to look at electron’s console logs but I don’t know what the keystroke is (maybe CTRL-W?). But, at times like this, I find it’s easier/faster for me to debug by using a different machine with Chrome/Firefox and load up the mirror that way by going to the rpi’s IP and port: http://10.0.0.1:8080 (assuming your rpi’s IP is 10.0.0.1, change it to match yours.) Black screen or not, you can always hit F12 on a windows browser and pull up the console log. Look for Javascript errors.

 Thanks KirAsh4 and RedNax! I resolved it. What happened was that I entered 
 location: ‘San Francisco’
 locationid: ‘5391959’on the currentweather module. I decided to delete the locationid key and left it blank and voila! It works now! You guys rock!

 @RedNax do you happen to know why my MMM-WunderGround module is not showing the forecast?

 Any errors in the console or the web inspector? https://forum.magicmirror.builders/topic/86/how-to-troubleshoot

 This module is fantastic, thank you. I was wondering about getting weather for multiple areas. Is there a way to do that within the program or would I need to copy the directory to say, MMM-WunderGround2?

 @Shockwave Thanks :) To use the module twice you can just enter multiple wunderground config sections in your config.js. It will then display both. There is no need to install the actual module twice.
