Missing Palette in my NodeRed menu

Hi!
I suddenly found that my Palette link in Node-Red menu have dissapeared.

Any I dea how I activate it ?

usually this means that you don't have npm installed as the palette requires npm to be available.
What does the console log say on start ?

Did you ever see it on this device?? I notice you are on an old relase of NR, it is at v1.0.6 currently.
