HWS-template (WD34) July version available

I want to use an official AQ station to display the AirQuality in my area so I get a APIkey at this site https://aqicn.org/data-platform/token/#/. I insert the API key in waqitoken field on w34_easyweathersetup.php but I get this error message:

Official AQ sensor station
Problem 55: No AQindex found
Check settings and data

What’s missing?
