You need to remove all references to PROGMEM. Here is the replacement:

// Create an ESP8266 WiFiClient class to connect to the MQTT server.
WiFiClient client;
 
// Setup the MQTT client class by passing in the WiFi client and MQTT server and login details.
Adafruit_MQTT_Client mqtt(&client, AIO_SERVER, AIO_SERVERPORT, AIO_USERNAME, AIO_KEY);
// Setup feeds for temperature & humidity
Adafruit_MQTT_Publish temperature = Adafruit_MQTT_Publish(&mqtt, AIO_USERNAME "/feeds/temperature");

Adafruit_MQTT_Publish humidity = Adafruit_MQTT_Publish(&mqtt, AIO_USERNAME "/feeds/humidity");

Hi johannes,

The replacement you oploadet is for the "temperature" and "humidity" project!?

I'm new, could you pleace give me the code where the lines is changed?

Thanks in advance!
