MMM-BackgroundSlideshow not showing images - Suspended?

[UncleRoger]

I’m using MMM-BackgroundSlideshow with MMM-Pages and it was working fine. My mirror was down for a while and when I booted it up again, it seemed to be working fine except that a bunch of modules needed updating – MMM-Traffic, MMM-EarthquakeAlerts, MMM-CalendarExt3, and MMM-BackgroundSlideshow.

Like an idiot, I updated them all (git pull/npm install) without backing things up first. I didn’t change the config except to add something to another module on a different page.

I have not reloaded the MM on the actual MM downstairs, but when I access it via a web browser from my computer, it doesn’t show any images.

I looked in the console and see that when switching to page 1 (images), it suspends the modules that were active on page 0, resumes a few always-on modules (MMM-Pages, MMM-Keypress, etc.) and then… suspends MMM-BackgroundSlideshow.

One other note - when I change pictures (mouse scrollwheel, picked up my MMM-Keypress and sent as a notification to MMM-BackgroundSlideshow), I see this error:

Displaying paintings is one of, if not the most important aspects of this for me so I’d really like to figure this out. Alas, I seem to be an idiot so…

Thanks in advance!

So I think the “Suspended” thing is a red herring. I booted up my dev system and watched the console messages there. I saw the same behaviour of BackgroundSlideshow being suspended but it does show the images.

I’ll update just MMM-BackgroundSlideshow on that system and see what happens.
