Images which have been embedded using the CDN link provided by Pasteboard are not currently displaying on this site. I have become aware of this problem on Monday 18 February 2019.
This affects all images uploaded at any time, not only new images. Around 500 posts (questions plus answers) could be affected. So this is a very serious problem, because a crucial part of questions or answers may be contained in the image.
What is going wrong and when will this problem be resolved?
