@sdetweil Thanks! I’ll keep an eye out for a solution.

@sdetweil It looks like electron.js in 2.23.0 already has those changes except for

let config = await core.start()

https://forum.magicmirror.builders/topic/17807/config-template-file-not-exists-no-ensubst/7?_=1685358870752 had the default settings for address and ipWhitelist. The new problem arises when I add my information.
Changing config to

address: "0.0.0.0",
ipWhitelist: [],

results in a blank electron screen:
npm run start

On a Win10 machine, MM doesn’t display the screen but I can access it through a web browser. Let me know if I can provide further info that will help troubleshoot this. Thank you for taking a look at this issue.

@sdetweil Thank you for taking a look at this. I forgot to put in the first post that the MM screen doesn’t start. If that message does not indicate an error, then I have another problem. Please let me know what else to try or what further info I can provide. Thanks!

Today I installed the current version of MM on Win10 in C:\MagicMirror. I had a previous version running without issue in C:\Users. I did not re-install Node. I am getting this message “Config template file not exists, no ensubst”. The rest of the loading messages seem normal with the last message being “Sockets connected and modules started”. Config:check does not find any errors. Here is my config.js

let config = {
	address: "localhost",	// Address to listen on, can be:
							// - "localhost", "127.0.0.1", "::1" to listen on loopback interface
							// - another specific IPv4/6 to listen on a specific interface
							// - "0.0.0.0", "::" to listen on any interface
							// Default, when address config is left out or empty, is "localhost"
	port: 8080,
	basePath: "/",			// The URL path where MagicMirror² is hosted. If you are using a Reverse proxy
					  		// you must set the sub path here. basePath must end with a /
	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"],

	useHttps: false, 		// Support HTTPS or not, default "false" will use HTTP
	httpsPrivateKey: "", 	// HTTPS private key path, only require when useHttps is true
	httpsCertificate: "", 	// HTTPS Certificate path, only require when useHttps is true

	language: "en",
	locale: "en-US",
	logLevel: ["INFO", "LOG", "WARN", "ERROR"], // Add "DEBUG" for even more logging
	timeFormat: 12,
	units: "imperial",

	modules: [
		{ // clock
			module: "clock",
			position: "top_left"
		},
	
	]
};

/*************** DO NOT EDIT THE LINE BELOW ***************/
if (typeof module !== "undefined") {module.exports = config;}

I would appreciate some help in troubleshooting this. Thank you for taking a look.

@sdetweil
Thanks! I will work on setting it up.

@sdetweil
Is AlexaControl still working?

@BKeyport
I have been working on a new install of MM to clean everything up. I worked on CalExt3Ag today and I hope this helps you. Here is my entire custom Css. I am using Firefox in Windows 10.

.CX3A_MAGIC {

.CX3A .event .headline .symbol {
  color: var(--calendarColor);
  font-size: 75%;
  vertical-align: text-bottom;
}
.CX3A .event .headline .symbol.noSymbol::after {
  /*content: '⬤';/**/
  content: '|';
  font-family: Impact;
  font-weight: bold;
  /*display: inline-block;
  /*padding-right: 2px;/**/
} 
 /**/
 
/*  ++++ Divider Lines +++ */
.CX3A .agenda .cell {

.CX3A .event .title {

  order: 1;
  width: 135px; /* Adjust for your region width. Here I am using fixed value to make things simple */
  text-overflow: ellipsis;

  padding-left: 2px;

}

.CX3A .event .time.startTime {

}

.CX3A .event .description {

  white-space: nowrap;
  text-overflow: ellipsis;
  max-width: 100%;
  font-size: 90%;
  color: orange;
  padding-left: 20px;

Looks like:

Changing only .CX3A .event .title.

/* +++  Event title +++ */ 
.CX3A .event .title {
  color: var(--calendarColor);
  order: 1;
  width: 135px; /* Adjust for your region width. Here I am using fixed value to make things simple */
  /*text-overflow: ellipsis;
  overflow: hidden;
  white-space: nowrap;/**/
  padding-left: 1px;
  flex-grow: 1;
}

Gives:

I think you are wanting the wrapping and I do not LOL.
