Hi there,
I don’t see it working since the first time I checked it. And that’s because the image in that place doesn’t exist, example,
https://eurekawellness.com.au/wp-content/uploads/2014/06/autoimmune-support-400x400.jpg
its original image is this
https://eurekawellness.com.au/wp-content/uploads/2014/06/autoimmune-support.jpg
You’ll have to regenerate your image thumbnails again, please install force regenerate thumbnails plugin and generate them.
Thanks!
