I want to set the weather layer, but it doesn't work.
When I check the Weather option in Settings tab, nothing happens.
I added the Openweathermap API key in the map Settings.
The key seems to work. When I try :
http://api.openweathermap.org/data/2.5/forecast?id=524901&appid=myAPIkey
I get a JSON response.
I check on your demo site... and the weather layer doesn't display either...
