I just started using Thingspeak. I'm totally new to IoT methods. The hardware is Huzzah esp8266 and DS18B20 one wire temperature sensor. Using Arduino IDE. This is sketch I'm using:

I can see the Temperature fine on Serial Terminal of IDE. I see WiFi Client connected and and then 230 Temperature: 19.94 But nothing on Thingspeak graph except "Add Visualizations"
I also see this over and over when I start this forum:
Warning: in_array() [function.in-array]: Wrong datatype for second argument in /home/content/56/7318356/html/community/wp-content/plugins/simple-press/forum/content/classes/sp-list-topic-class.php on line 337
I'm lost!
