I ran into what Pat did,
"If you have never run the New Permissions tool, or are upgrading from a version prior to v5.0-rc9, then you MUST run the New Permissions tool, even if you have run it before. It's on the v6 Tools page." Is this a typo? Should it be the V5 utilities page?
I copied my V5 Backup back to flash, will run permissions util, if no luck with that I will try the make bootable.
up and running now. To get upgrade to work I followed the plugin steps, moved flash drive to PC, DL the V6 zip and copied the syslinux file to the flash drive, then ran the makebootable bat file. (running makebootable does not work after plugin upgrade since syslinux folder did not exist) Then moved flash drive back to unraid server, and powered back up.
