I have had that all day and it just stays like that. The thing is I set it up so it will show the little pop-up thumbnail fine but won't show the thumbnail on the actual post. It shows the exact same image above, website thumbail Generator Thumbnail Queued......Not sure what to do?
Q. What does 'Thumbnail Queued' mean?
A. Sometimes you may see an image that says 'Thumbnail Queued' on it. This means that you are the first person to request that particular website and that it will be captured as a thumbnail as soon as possible. Typically this takes less than a minute.
Note: IF the request showed before but is now showing as 'Thumbnail Queued', it was most likely deleted by retention. Read more here: Retention Policy.
Note2: If you have refreshed the image and it displays properly in your history (while logged into the ShrinkTheWeb portal), then you are most likely viewing a "browser cached image" and need to refresh your browser using [ALT]+[F5].
