AFAIK, Getting token script itself is executable on any environment, as far as it has node and browser. (and properly installed)

node generate_token_v2.js

Usually it should show some instructions to open a browser and navigate URL for OAUTH process. But if you get nothing(even error message) hmmm. Weird. Could you tell us more details or captures?

@sdetweil I have the one from the docs indeed.

{ module: 'MMM-ImageSlideshow', position: 'bottom_center', config: { imagePaths: ['modules/MMM-ImageSlideshow/exampleImages'], } },

or I also tried this to have two elements

{ module: 'MMM-ImageSlideshow', position: 'bottom_center', config: { imagePaths: ['modules/MMM-ImageSlideshow/exampleImages','modules/words/'], } },
