leafletJS files are missing

Hi, this error appeared only in the article pages:

Travelers’ Map is loading…
If you see this after your page is loaded completely, leafletJS files are missing.

while in pages or categories it works:
https://www.fotografodiguerra.it/tag/grande-guerra-sul-piave/
I tried to reinstall the plugin and bypass it from compression but to no avail.
I also tried to create a post only with [travelers-map] but it still doesn’t work.

This is the error in Chrome Console:

Uncaught Error: Map container not found.
    at i._initContainer (leaflet.js?ver=5.7.2:5)
    at initialize (leaflet.js?ver=5.7.2:5)
    at new i (leaflet.js?ver=5.7.2:5)

    at initTravelersMap (travelersmap.js?ver=5.7.2:37)
    at HTMLDocument.<anonymous> (travelersmap.js?ver=5.7.2:346)
