When I issue the ps -ef | grep node
it returns pi 988 811 3 17:20 pts/0 00:00:00 grep --color=auto node

Just checked and the module name in the module directory is
MMM-darkSkyForecast and that was created by git cloning as stated in the instructions from the GitHub Repository.

So the name of the directory DOES have a lowercase d in it.

How about I do a full shut down /power off?

Ahh looks like the console was behind Magic Mirror and has these entries.

Well that did not display the DEV console either. Just Magic Mirror standard display. I have my display rotated 90 degree’s if thats a concern. So its in Portrait Mode essentially and not Landscape.

Yup. Thats what I pressed CTRL-SHIFT-lowercase i. Nothing. Strange eh? I will try the method above.

I press CTRL-SHIFT-I with Magic Mirror Running and no console is presented. Actually there is no change at all. Its as if I have not pressed any keys.

Latest version of Magic Mirror on Raspberry Pi Zero W.
Git cloned directory for MMM-DarkSkyForecast. Directory created under MagicMirror/Modules. Ran npm install. . Installed and mentioned 16 severe vulnerabilities.
Whatever?
Modified /config/config.js with entries from git hub repositiory instructions.
Ran linter against config.js. No lint :)
Restarted Magic Mirror. Module does not display. Here is my config.js

That works. Now I am struggling with understanding the IP Whitelist area . I want to open up access to all IP Addresses internally between 192.168.1.2 and 192.168.1.254 as I am unsure which of those IP addresses will be dynamically assigned to the device I use to access the MMM-Remote-Control app.

ipWhitelist: ["127.0.0.1", "::ffff:127.0.0.1", "::1"], // Set [] to allow all IP addresses
	                                                       // or add a specific IPv4 of 192.168.1.5 :
	                                                       // ["127.0.0.1", "::ffff:127.0.0.1", "::1", "::ffff:192.168.1.5"],
	                                                       // or IPv4 range of 192.168.3.0 --> 192.168.3.15 use CIDR format :
	                                                       // ["127.0.0.1", "::ffff:127.0.0.1", "::1", "::ffff:192.168.3.0/28"],
