I am still a beginner but one of my best tipps so far:
Don’t use a cheap SD card and make constant backups.
For backups I use Win32DiskImager and WinSCP

@MWel1977
There are many threads concerning that topic
This might be the wrong place to continue that discussion. Just comment under my video

I use a module which I have found on github but is not published under the 3rd party modules

@MWel1977
That is very easy and just a module you have to install:
https://github.com/Jopyth/MMM-Remote-Control

and I don’t know anything about programming or linux. My YouTube playlist shows what I have achieved so far

@MWel1977
I am a beginner and use VNC viewer (which has a desktop view of my Raspi) on my work computer and my android smartphone

@shgmongohh
I use MMM-PIR-Sensor and it works just fine on 2.7.1
https://github.com/paviro/MMM-PIR-Sensor

@DæmonEyes
me again
have you tried sudo npm audit fix?

@jhwwhite
Great, I am glad that worked for you, too!

@DæmonEyes
This is what worked for me but I am a beginner, too
Inside the MagicMirror directory:
git stash
Then
git pull
Then
npm install
After that search for modules that use package.json files, go to their directories and
npm install

@DæmonEyes
Just fill in your github user email and username

@jhwwhite
I had a similar problem.
Have you tried this?
Inside the MagicMirror directory:
git stash
Then
git pull
Then
npm install
Afte that search in which module the package file is located and
npm install

@Kugelfang
I am really no expert at all but here is another tipp of mine:
I also use these modules to turn off my monitor:
MMM-ModuleScheduler + MMM-Remote-Control (at a certain time)
and MMM-NetworkScanner (when my phone is not connected to my WLAN)

@Kugelfang
Hi, I updated to 2.7.1 yesterday and also installed MMM-PIR-Sensor which works fine for me (https://youtu.be/5Cs3pCZamuM)
I am not using the Full KMS driver though
Did you follow these steps also:
Execute npm install to install the node dependencies.
Add your user (pi?) to the gpio group by executing sudo usermod -a -G gpio pi.
Execute sudo chmod u+s /opt/vc/bin/tvservice && sudo chmod u+s /bin/chvt to allow turning on/off the hdmi output.
Reboot your Pi.

@dxfan227
Thanks a lot!
I used Mirropane™ Chrome Spy glas, 4 mm thick, next time I might get 6 mm.
PIR hardware: https://amzn.to/2YNSxYr
Module: https://github.com/paviro/MMM-PIR-Sensor

New update with PIR sensor and new modules: Wunderlist to-dos, SoccerLiveScore & fuel prices in a range of a certain distance to my home:

@sdetweil said in Blank screen after updating tonight...:

git stash

Thanks for your quick reply and your tipp that worked for me.
After git stash I updated MM to 2.7.1 and then I cd 'ed into every installed module and did npm install.

Excuse my bad English and sorry to bug you and thanks again fpr your time!

Noob from Germany

@sdetweil

Sorry, I am a beginner from Germany. Maybe you can help.

It won’t let me update because of this message:
“Ihre lokalen Änderungen in den folgenden Dateien würden durch den Merge überschrieben werden”
which translates to:
“Your local changes in the following files would be overwritten by the merge”
and then it lists like 5 or 6 package.json files. What can I do?

Danke/Thanks!

@eskudo12791
try this:
fade: false,

Now also with Local Transport module:

Nun wird mir morgens auf dem Magic Mirror meine tägliche Pendelstrecke über die Google Maps API angezeigt.
