          I’m sure.I don’t think SolarPicture could be the problem.

          Yes, the error keep showing

            @nowayto wild, lets do this… intall MM again, but save the current…

            #backup MM config and modules list
            bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror-backup-restore/main/mm_backup.sh)"
            #rename the MagicMirror folder out of the way
            cd ~
            mv MagicMirror MagicMirror.save
            #and install MM again
            bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)"
            #restore the  MM config and modules
            bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror-backup-restore/main/mm_restore.sh)" 
            

            then

            cd ~/MagicMirror
            npm start

              Before writing here I made backups, locally and on github, like you taught me in the past :)

              Now I’ll try

                That’s incredible… I did it, everything goes good… no issues but when I start it

                npm start

                magicmirror@2.31.0 start
                npm run start:x11

                  @nowayto wow!!! NOW i am really confused.

                  have you rebooted?

                  if you try the sample config.js

                  cd ~/MagicMirror/config
                  mv config.js config.js.save
                  cp config.js.sample config.js
                  

                  and then
                  npm start

                  does it run or fail

                    Sam… I don’t know how to saying it.
                    I figure out the issue.

                    After your last message I tried what you suggest.
                    With the default cfg I had no errors, with mine I had errors.

                    So I checked again and again the config…
                    and I find an underscore _ right at the start of the config

                    npm config:check told me “no syntax errors” and that confusing me.

                    When I edit it I use nano editor
                    I do “sudo nano config.js” and I press CTRL + _ to jump at the 250 line.
                    Might be one of the latest time I opened it and press _ a bit faster than CTRL and I add it for error.

                    In addition I notice that when I open config.js with nano editor the green cursor is, clearly, at the start of the first line… EXACTLY on the undescore _ and it hides it.

                    I’m really sorry for bothering you with that.
                    How can I buy you a coffee ?
                    Thanks

                      @nowayto no coffee needed, we found it!!!

                      please NEVER use sudo inside MagicMirror folder
                      no reason to use super user , just makes trouble later

                      so if you fix the config.js in the saved MagicMirror folder then it should run ok too!!!"

                      ill see what we can do about the misleading message… thanks for your energy here!!!

                          @nowayto ok, I’ve found the error producer
                          and I’ll propose a fix…

                          I think this might have been more useful lol

                            @sdetweil Ok but I wanna just offer a coffe for your kind and your time spent with that.

                            Do you suggest me to fix the old magic mirror folder or just rm it?

                              @nowayto if you have everything working, you can rm it

                              i was just saying you could prove this change would fix the prior install

                              i do this for fun, really! pay it forward, help someone else on whatever when you can.
