The page went missing

Bug Report

Good morning,

Our voting page went missing https://atlas-collaboration-nominations.web.cern.ch/form/top-combination-convener-2022
When I go to the list of all the webforms, I get “The website encountered an unexpected error. Please try again later.”
Could you please help to revive our page and the submitted answers?

Kind regards,
Lina

Hey Lina, just cross-posting from our private chat that we resolved this issue today.
Your website broke after the Drupal 9 upgrade and I restored it by reverting to the backup from right before the upgrade.
However, this means that it is still on Drupal 8 and will have to be upgraded ASAP.
