Advice with Semantic Maps

From semantic-mediawiki.org

Going back to basics, I can confirm that I've just installed a completely fresh MediaWiki instance, and installed the Semantic Bundle following instructions, uncommenting just Maps and Semantic Maps in SemanticBundleSettings and trying the following:

Page (which works as expected):

{{#display_map: 52.8205, 1.5371}}
[[Has coordinates::52.8205, 1.5371]]
[[Category:Locations]]

Main Page (which shows coordinates in the table but no markers on the map):

{{
#ask:
[[Category:Locations]]
| ?Has coordinates
| format=table
}}

{{
#ask:
[[Category:Locations]]
| ?Has coordinates
| format=map
}}

Same here. Can't make it work. Is there some debugging code we could generate ?

Except for features that require an API key, like layers (and other problem ...)
I believe that the coordinates are ok (they are produced with geocoding in a semantic forms template) and if I understand right, it also should work with addresses.

... but maybe I am a bit blind to a little mistake, since I am very new to this.
