Blank Black screen after the last - 2.11 - update

[kondef]

I just unfortunately did the update of 2.11 backing up only the modules folder and config.cs file. Now with either npm start or npm run start, nothing happens. I have a black blank screen. I followed the instructions of MichMich with the commands git pull && npm install.How can i fix that problems guys? Please consider that i am not expert with programming so please explain in a simple way. My node versions is:10.19

@kondef what kind of pi?

u will also have to do npm install in any module folder that has a package.json file

I think my upgrade script will work, haven’t had a chance to try myself (trying to fix install)

I also had it with me, that’s because of the MMM-Pir-Sensor module. I deactivated it for now.

@sdetweil I have raspberry pi3 b+. I reinstalled npm for all modules that have json file but i am still getting the same problem!

@kondef r u using pm2 to start?

If so do

pm2 logs
ctrl-c to exit

Then npm start

Also may need to open developers window, ctrl-shift-i on the keyboard, select the console tab and scroll up to see any errors…

@sdetweil No i start manually npm start

[sdetweil]

@kondef so, you should open the dev window

[kondef]

@sdetweil You mean npm run start dev ? I am sorry i told you i am not expert. By pressing Control - Shift - i the only thing happens is a small window opens.

[sdetweil]

@kondef should be the right side of screen

npm start dev can do the same on startup

I am getting “DevTools was disconnected from the page. Once page is reloaded, DevTools will automatically reconnect” and the page now is white blank and thre is nothing on the dev console.
But i managed to take a photo while magic mirror was loading and i got the following: "MODULE NOT FOUND. Require Stack /home/pi/MagicMirror/modules/MMM-Hotword/snowboy/lib/node/index.js
