 @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

 @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.jsand then 
 npm startdoes it run or fail 
- 
 @sdetweil 
 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 confignpm 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 laterso 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 i use ctrl-end on my keyboard for nano to get to end of file haven’t found a way to do that on my chromebook, drives me crazy!!!
