Having the same issue – files aren’t transferring to S3. I’m testing from two sites, both using the same server. Works fine on one, but not the other.
Downgraded to the older Joetan plugin and problem persists. Leads me to think there’s something in the original code base prior to the fork made by Bradt. Disabled all plugins and still can’t figure out why it works on one site, but not the other.
The problem is a compatibility issue between Clipcart 1.2 and Cart66 Lite 1.4.9. Downgrading to Cart66 Lite 1.4.8 fixes the problem until next versions of Cart66 and Clipcart.
