Hello

From earlier today a project i've been working on has stopped working. It was working for the last couple of weeks with no coding updates in the mean time.

The error i'm only now getting is

"from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource."

Im transferring four readings from thingspeak to a web page

the get command i'm using is. xhttp.open("GET", "https://api.thingspeak.com/channels/752230/feeds/last", false); xhttp.send();

Why would i only start receiving this error today. If more information is needed i will send it on.

any insights would be much appreciated.

Thanks

Trev
