I'm trying to build interactives maps, with Maps and Semantic Mediawiki but so far i have one issue i don't find any clue to resolve it.
When i create a property:coordinates and assign it the type "_geo", i have an error message saying that semantic can't find the Maps extension.
(you can see the error here : https://eana.miraheze.org/wiki/Spécial:Types/Coordonnées_géographiques)
The error prevents me to add coordinates to my pages, and to have leaflet queries. (sandbox here : https://eana.miraheze.org/wiki/Utilisateur:Lucastucious)
