Hi. I think this module does not support multiple instances. However you can check this topic where the same question is discussed.
I have looked at various discussions and I have duplicated the module that I have called MMM-NewsFeed2 and I have replaced in the various .js the name MMM-NewsFeed with MMM-NewsFeed2.
The two instances are launched but remain overlapping. The second instance (MMM-NewsFeed2) does not respect the position assigned in configuration.
Bugsounet can you help us understand how to duplicate this module?
Thank you all.
