gnome-shell-extension-openweather not working

[Andre Robatino]

For most of the past day, gnome-shell-extension-openweather is not working,
and it just says "Loading" when clicking on it. If I go to the website, and
enter the zip code for my city, it shows the forecast, but the city link is
just "http://openweathermap.org/city/0" which points to "City of London,
GB". Was there an API change or something?
