OK. I downloaded the thumbnail folder from my live site and the test site is now fully functional.
I’d still like to know why clearing the cache deletes that folder though.

ctpl simply deletes the /var/cache/templates/ folder and ct deletes /images/thumbnails/ one
Yeah sorry, what I meant was, I'd still like to know why that folder isn't recreated and the thumbnails regenerated after clearing the thumnbnail cache.
