bazab Hi. Here is a message from a page where Yahoo Weather API was before:
Important EOL Notice: As of Thursday, Jan. 3, 2019, the weather.yahooapis.com and query.yahooapis.com for Yahoo Weather API will be retired.
They will change it to a different server as I've seen in the forum, but I do not think it works yet. I believe we will update the extension as soon as this will be valid.
