I just tried to do a fresh install of this plug-in.
I copied the link from github to the folder.view.plg
Install went fine. Said it completed and installed the newest version.
No joy. Upon further inspection, it made a folder.view folder, added docker.json,vm.json and the folder.view-2025.02.26.txz file. It also made 2 folders scripts and styles. There are no other files. It did not extract the .txz file.
To make the plugin work, I had to manually extract the .txz file and upload all the files to the folder.view file and reboot Unraid.
The plug-in works, but the install needs some tweaking apparently.
