photos not displaying

Posts display fine but where there is an image attached to the post the images are no longer displaying in the feed on my wordpress sites.

I have this installed on two different sites and it’s the same on both sites.

Any insight you can provide to get the pictures to show on the feed would be greatly appreciated.

you can see an example at https://www.marandosrestaurant.com
