Thanks for checking, now I know it is not caused by my setup.Same error for me in Iceland. I have to remove the lat & long and use Yahoo as the provider to get weather info. It used to work in previous version.
... I realy think there is something wrong here ...
please find the hotfix version v1.2.1 of WorldWeather at the first post of this thread and in our plugin repository.... Same error for me in Iceland ...
