I followed this tutorial to get the google plus count, everything work fine if I follow 100%. But If I like to create my own API key from google developers console, then i keep getting the above error.
Things i have did but still failed
- Create Server API Key from both new and old Developers console (not sure some say old console able to solve this issue)
- Enable Almost all API under APIS.
- Try to key in my public IP in "Allowed IP" or leave it blank.
Anything I did wrong?
