WunderWeather Weather reports Error: Http error 500: internal server error.

Example commands to reproduce:

/msg Limnoria weather Kotka
/msg Limnoria weather Helsinki
/msg Limnoria weather Buenos Aires, Argentina

I think this applies to all instances though and this has been the case for days.

I guess this is caused by https://www.wunderground.com/weather/api saying

To improve our services and enhance our relationship with our users, we will no longer provide free weather API keys as part of our program. If you have been directed to download our Weather Underground free API key by a third party provider, please contact your vendor for resolution.

Are there any recommended alternative Weather plugins?
