Images Not Showing

Hi Danny
I have gone through all of the images problem forums on this support forum.
But none of the solutions are helping.

My Facebook feed images are not showing up, I have left the image sizes to default and set sizes, as well as choosing the thumbnail option.

Nothing is working. Could you please advise.
