Map pins not appearing on public map

I’ve been adding a lot photos and content lately and just noticed that all my map pins have disappeared from the map at the top of the homepage. All the other map pins are fine on each item page and for each tour. The site is explorebig.org

There’s an error occurring in what I assume is the data used to populate that map:

https://explorebig.org/items/browse?output=mobile-json

You can follow the linked instructions from that error page to enable error reporting and see what’s going on.

Thanks. We don’t host the site, so I will contact the host.
