I'm using site Thingspeak.com for storing data from my sensors.
Aprox 2 days ago it apear the error message:
I can not use any more: "getJSON request failed!"
It is not about cookies, because even in private windows I get same error.
Firefox in debug windows yelling:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.thingspeak.com/channels/795411/feed.json?&offset=0&results=2500;key=Z67C5TON0V5UU0M6. (Reason: CORS header 'Access-Control-Allow-Origin' missing).
My script worked till now, and I didn't change nothing on it. This errpr does not depent on browser.
What I need to change to be able to use again?
