Michelle Zimmer is having a problem with the plugin she's using for the map on her Brewery page. When I browse it, her markers are there (she reports the same) but the map tiles don't load and produce an error. Oddly, when I zoom in or out the tiles briefly show before the error pops up again.
I wrote to her asking for more info. She replied:
"Yeah, it is odd. Also, when I expand the individual markers, the map loads without an error.
Yes, it is the Leaflet plug -in."

There are two problems.
One is that the plugin doesn't properly try to load HTTPS assets. So the browser prevents them from being loaded. See https://wordpress.org/support/topic/map-tiles-still-loaded-via-http-instead-of-https/.
The other is that the API providers appear to have changed their endpoint URLs, and they haven't been updated in the plugin. See https://wordpress.org/support/topic/discomap-api-endpoints-have-changed/. I've made the manual change on the brewingbronx site, and it appears that maps are loading properly.
I'll have to do something more general to fix the problem across the Commons, until the plugin author fixes it in the plugin. Depending on the upstream fix, a local fix may be necessary even after an update. I'll try to do this for the next Commons release.

To be clear, the specific page I was given should already be fixed. https://brewingbronx.commons.gc.cuny.edu/german-brewers/
If there are more maps that aren't working, give me the URLs and I can fix them directly.

aha!! that's great. thanks. Marilyn, can you also say that I requested that Michelle add to the thread she started in the GIS group but that anyone else facing this problem should let us know, as the larger issue with the plugin won't be fixed until our Feb 13 update?

I've put a fix in place that should work for all Commons sites. https://github.com/cuny-academic-commons/cac/commit/1018c30ebfbdfbf59ff81c35e828bc594421667e
