All of a sudden, thumbs are not showing in Assets. The folders are being created in the cache/assets/thumbs folders when files are uploaded, but no image is generated.

    Have you checked the permissions on the affected folders? Perhaps there's a setting that's off? Has anything changed on your server and/or code recently?
