Ahh just found out OSM uses bing’s aerial imagery so that explains that one.
You should see a URL being pulled [librenms install]/overview/leaflet.markercluster.js.map or [librenms install]/js/leaflet.markercluster.js.map
it could be a side affect related to https://github.com/librenms/librenms/pull/10091 , you could try set
your $config['install_dir'] to /opt/librenms or where you installed it, then the base_url should be set, so try that, and then try the stable branch as a test.
Does the world map show on a dashboard widget or url/fullscreenmap/ ?
