I maintain a video site. We use On Demand theme which supports featured images. Post have embeded video, mostly from YouTube, and we use Video Thumbnails plugin to locate and upload video thumbnails on YoiTube, Vimeo, etc to the Wordmedia media libay for use as featured images.
Video Thumbnails plugin won’t find the thumbnails until the post is published. And then, it sometimes is necessary to try once more to retrieve the thumbnail and update the post.
The problem is, once the post is published, even with “Add Link to Facebook” NOT checked, a ink will NOT appear when the post is updated with “Add Link to Facebook” checked.
I have also tried cghanging post status to daft, then re-publishing. That won’t work either.
Why should this be the case? Can this problem be fixed?
