Mavericks - Dashboard Weather Widget stopped working
My Dashboard Weather Widgets have suddenly stopped working. Or, to be more precise, the two I have open since forever still work normally, but when I add a new one and try to type in a city (any city, even if it's the same one as one of the two already open) I always get the same Validating... and then No cities found.
Any ideas? I would hate to lose this, apart from the Unit Converter it's by far my most-used and beloved thing on the Dashboard.
