I followed the description thread how to configure the new version of the GK Weather App:
https://www.joomlart.com/forums/d/19681-how-to-configure-display-the-latest-gk-weather-1-8-module/7
... but it says there is no need to enter the "Callback Domain".. however ... Yahoo has set that to "required", so what domain is that - what is a "valid" URI? No matter what domain I add there.. with http:// or www. or without... it always says the domain is not valid.
How can I use this version of Module? It worked so many years ... until now.
