Well, we try to module for years and I think I give up now. We always have error.
Admin always answer: Yes and I answered the question a lot of time.
And the answer is:
You need to enable cache from SP Weather module's advanced parameter.
Increase cache times 60 minutes. It collect data from Google weather. Too many request block it.
But in case, if you do that and Google bug, you are gonna have the error message for 60min. Really, it's just not working, and looks like he don't know how to fix this, so until he fix this problem, forget about this, it's gonna broke your website all the time.
Let's see in the future for an other try maybe!
