<![CDATA[Black screen when starting MM...]]>Hello all,

So, it’s been a while since I’ve worked on MM. So, I just recently upgraded my PI3 and updated MM as well to the latest version. I’m getting a black screen whenever I’m starting MM. This is what I’m getting after running /npm start…(any help is appreciated)

ctrl-r will reload
ctrl-q will quit
ctrl-m will minimize

all same as on Windows for full screen apps

Eventually, I was just “x” out of the terminal window. Again, thank you for the help.

It’s finally working with your help. My calendar is up and running. But another quick question, I’m using npm start to start the calendar. How would I stop the calendar? Again, Thank you!
