      @olesoncrypto this is typically caused by a missing library.

      we removed some, and it turns out modules didn’t document using them

      look at the pm2 log

      command

      pm2 logs --lines=100
      

      looking for module not found.

      for each of those, go to the module folder
      if there is NOT a package.json file do

      npm init -y
      

      then in either case do

      npm install xxx -- save
      

      where xx is the name of the not found thing

      we know about
      request
      rrule-alt
      and
      valid-url

      then restart mm

        0|mmstart  | /home/pi/MagicMirror/js/app.js:20
        0|mmstart  | Log.log("Starting MagicMirror: v" + global.version);
        0|mmstart  |     ^
        0|mmstart  | TypeError: Log.log is not a function
        

        I’m not sure how to fix this one. I nano’d into the file and they show a bunch of these log.log within the app.js file

          @olesoncrypto yeh, its provided by the logger

          so,

          give me output of
          node -v
          and npm -v

          if u rename your config.js to save.config.js (mv is the rename command in lnux)
          and copy the sample.config.js to config.js (in the config folder)

          does it work ?

            @sdetweil I was able to finally make it work! I just completed deleted the MagicMirror with sudo rm -r ~/MagicMirror and then reinstalled it. I copied the config.js.sample to my real config.js file. I ran that and it finally worked! I was fixing it up and then it happened again as I was imputing parts of my old code. I realized that my issue was that I had the useHTTPs: "false", instead of useHTTPs: false, which was the real reason there was just a blank screen. I appreciate your time and effort to help me out, especially with the fast responses. You’re a true life saver @sdetweil 🙂

                @olesoncrypto yes, that will get you

                general rules for config.js

                
                the thing to the left of :  does not need quotes
                for the thing to the right of : 
                      if it is a number (9, -1.234) or true/false  , no quotes
                      if it contains a letter 12ff234, bob,   then needs quotes, 
                         
                single or double doesn't matter  as long as they are the same start and end
                
                every { needs a  matching }
                every [ needs a  matching ]
                
                [] is a list [ 1,2,3,4] or [ first,second,third]
                {} is a structure/object with name/value pairs  
                    {    x: value, y: othervalue }
                
                u can write lists and objects all on one line (what a pain)
                or across multiple lines... (much more readable)
                    BUT, you STILL need the commas between items in either 
                
                if u get an error, unexpected token, 99% of the time, 
                u forgot a trailing comma on the line ABOVE the one reported (error on line 45, look at line 44)
                
                a good debug process is to join the list or object to a single line in your editor,
                 and get the , between the items, then split it again after each comma...  
                so u have a separate item on each line.
