I figured it might be a compatibility problem, so I tested [leaflet-map] in a shortcode-block. Didn’t work in 3.0.0.
I tested [leaflet-map zoom=11 address=”Liessel,Noord-Brabant, Nederland”]
[leaflet-marker message=”Liessel” visible] in 2.23.3, it worked. I upgrade to 3.0.0, it stopped working.
I tried it on two websites.
