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

          @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

              [email protected] start
              npm run start:x11

              [email protected] start:x11
              DISPLAY=“${DISPLAY:=:0}” ./node_modules/.bin/electron js/electron.js

                @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

                        [ERROR] fatal error in /home/sam/MagicMirror/config/config.js at line 19 column 1,  _ is not defined
