Unable to archive and delete old milestones using the web UI
I'm trying to remove the oldest milestone builds from https://download.eclipse.org/modeling/emf/validation/updates/milestones/
I'm logged in, selected the relevant folders and hit "Move selected to archive.eclipse.org" as a first step.
They all fail with "Folder cannot be archived: failed with 256. Please contact webmaster.":
"Go to archives" sends me to https://archive.eclipse.org/modeling/emf/validation/updates/milestones/ but I get a "Not found".
