Thanks jonnyauk — that was the cause for me — the HTML was truncated due to an HTML bug.
It might relate to the end of file names, e.g., ‘-240×61.png’.
Breaks for me too. Also, it forgot my S3 key.
It’s a great plugin. Good luck fixing it soon.
Kind of a critical tone for a free plugin.
You realize that you can drag/drop your posts?
I agree that some way to filter & select posts, as a starting point for manually grouping them into hierarchies, could be useful.
