[variada]

also got error messages since updating to 2.0.10 (can't copy those atm, will do later if wanted)

could that be related to the hourly weather data that's missing since the update?

[ghost]

Daily forecasts are missing here with 2.0.10 too.

Edit: removed log, as it contains private data

[variada]

hourly forecast is back with 2.0.11 - thanks for the quick bugfix :)
