Once again, thank you very much for all your help with this. This is a really amazing piece of software and I continue to be impressed with the features.
I think I did run across an odd bug. When you upload a file via file-sync everything seems to work well. But when you upload a file via the webpage interface it doesn't seem to ever realize it has a thumbnail. As you can see here the three files "Aline" were STLs uploaded via the interface. The second screen shot shows that the thumbnail was generated by the system in the proper place. However no matter what I do when I refresh, log in, log out, switch computers, or run the thumbnail cron it doesn't seem to trigger these to show the thumbnail.
When you look at the file in the list it appears to have the green 3d.png box icon hard coded as the thumbnail rather than the cached thumbnail.
Is there anything you'd like me to test or try?
