If you want to get started: Check out my little Ionic Weather Application demo (Open Source)

Hi, I've been experimenting with this project and I have some issues. I can successfully run it on my phone but when I try to add a new location I get the "Error adding location" popup. When I try the Get location button I get "Error retrieving current location". I have WI-FI and GPS turned on. What can be causing this problem and how can I fix it?
Thank you in advance
