I have a blog post here. When I share this on Facebook the preview image doesn’t show.
I’ve tried re-scraping with the facebook developer tool It gives no errors and shows the correct og:image tag but does not update the preview image.
<meta property="og:image" content="http://gingerslist.com/blog/wp-content/uploads/2015/11/blossom-233838_1920.jpg" />
The current image is 1920 x 1276, which is well above the 200×200 requirement. It’s 304KB, nowhere near the 8MB size limit. I’ve tried shrinking it with no luck.
I’ve tried setting is as the featured image and as the first image in the post. Nothing helps.
