Mileages on "[Plugin: Weather Underground] Forecasts not displaying - invalidkey/The location could not be found"

Neither the widget nor the shortcodes are working on my site. The widget displays "invalidkey" and the shortcode displays "The location could not be found."

We've tried entering the location in each different format but with no success.

Hi, I have a same problem suddently this appears instead of widget "There was an error fetching the forecast: invalidkey". Any ideay?

Same here, we have it happening on multiple sites. Well, all sites using the widget actually. I presume this has to do with Yahoo again, maybe? There was a similar problem back in March.

I'll just wait for an update here, I guess?
