Card image not displayed, no errors apparently



Description of issue:
The image for the card looks just ignored.

URL affected (must be public):

The card validator does not complain, but the image is not displayed.

Tried many things as og:image og:image:secure_url, specifying type, width, height… no results.
Even image with wrong path does not trigger any error…


ok, looks cache issue with robots.txt
