I had the darksky API and the weather module was working fine until two weeks ago. I figured at that time darksky shut down their API and I needed to switch to Open Weather.
I followed the instructions, created an API key and added it to the weather module configuration. The weather region is still blank on 4 displays (different layout on 3, but the weather config is the same for all 4).
I upgraded to 3.0.2 thinking it was a problem with 2.3.7, but I still have blank weather. Luckily it’s mostly hot and sunny in Phx, and my colleague has suggested I replace the weather with a sun icon. 
Suggestions?
