I completed the upgrade from 11.0.3 > 12.0.0 via Silent Upgrade. Everything seems fine in Sugar instance, except I cannot open any documents that were added to Sugar prior to the upgrade:
I checked inside my ./upload directory, and it looks like Sugar has moved all of the old upload files into a new subdirectory (also called upload) during the upgrade process. So all the old files are now in ./upload/upload.
I tried resetting ownership/permissions on the entire ./upload directory, ran QRR, rebuild relationships, cleared /cache, changed the /upload/ filepath in config.php to /upload/upload/, removed the extra /upload subdirectory, but nothing worked.
Seems like the default /upload directory structure was changed with this update, but how do I get my old uploads to be mapped properly so we can access them in Sugar?
