Thanks for this info, i've managed to log what happened and found my mistake :)
I was using this in my config file :
"geodiv":
{
"provider": {"name": "vector", "driver": "GeoJSON", "parameters": {"file": "geodiv.json"}},
"preview": {"lat": "48", "lon": "-4", "zoom": "7", "ext": "geojson"},
"projection": "spherical mercator",
"allowed origin": "*",
"spacing": "16"
},
Instead of using the right syntax :
"geodiv":
{
"provider": {"name": "vector", "driver": "GeoJSON", "parameters": {"file": "geodiv.json"}, "spacing": "16"},
"preview": {"lat": "48", "lon": "-4", "zoom": "7", "ext": "geojson"},
"projection": "spherical mercator",
"allowed origin": "*"
},
The spacing parameter had to be in the provider part of arguments, problem solved.
Anyway, the tutorial i was talking about in my first post here is now online here :

Thanks again ++
