uno, weather shield, wifi shield not working together

Hi all,

like many newbies I’d thougth to get started with a [Weather Shield on my Arduino Uno and it works fine. Next I added the [CC300 WiFi Shield. Works fine on its own in the Arduino as well. Putting both of them on the Arduino and merging code into one and upload the sketch … and then it stops. I’ve narrowed it down via debug text messages to the following line of code:

Serial.println(myWeather.readHumidity())

While the code is commented the Arduino connects to the WiFi and prints debug messages showing its is moving properly through the sketch. As soon as I uncomment the code it doesn’t even connect to the WiFi anymore, it doesn’t even get to this piece of code.

My question: any ideas about what could be the cause of this? Do both shields interfere with each other? What can I do to solve it?

Thanks,
