Howdy,
It appears the image you have specified does not exist. When viewing the source of your homepage, the og:image is https://www.weirdtalesdesigns.com/wp-content/uploads/2019/09/FB.jpg
If you enter that image path into your browser you get a 404. Perhaps you deleted it?
If it hasn’t been deleted, then something else if preventing it from being access. Either way, it’s not the fault of the plugin.
