Hi again Jarad,
Our developer was also unable to reproduce... unless he messed with the Nginx configuration settings. Specifically, if this block was missing:
location ~* ^/uploads/r/(.*)$ {
include /etc/nginx/fastcgi_params;
set $index /index.php;
fastcgi_param SCRIPT_FILENAME $document_root$index;
fastcgi_param SCRIPT_NAME $index;
fastcgi_pass atom;
}
Then he was able to reproduce.
I'm sharing this in case it helps anyone else in the future coming across this thread. In the meantime, I've filed an internal ticket in our support system so we can investigate your hosted site, and we'll be following up with you via our usual client channels once someone has investigated further.
If, in the course of this, we learn anything else helpful to other users, I'll update this thread accordingly.
