About two or three days ago when I accessed the web where the Iframes are embedded, some of them displayed a red "Field value unavailable" warning. This was not happening before and is not a problem with the data, because on the thingspeak website they are displayed without any problems. Also, when you leave the web open for a while, these warnings disappear, but whenever you load the web, they are displayed again.
