I'm using the built in Iframe widget to display a customised Dark Sky URL to give local weather. When I do so, the weather displays but so too does the iframe warning that the content cannot be displayed?! HAs anyone seen this?
Since content loaded in from a different domain cannot be verified this image is always shown in the background, assuming the website being inserted has a background image or color. Apparently this widget doesn't have a background thus the image is coming through. You could:
Find another widget which does have a background
Make a custom widget which works similar to the iframe widget using the following HTML: <iframe id="forecast_embed" type="text/html" src="[YOUR LINK]" frameborder="0" height="245" width="100%"> </iframe> (info on custom widgets can be found here)
