Last Friday morning, I tried to upgrade the website from Drupal 9 to Drupal 10. I always do a backup, but I did not this time, and the upgrade went wrong. If you got to the website, you might have noticed PHP errors. I tried to recover what I broke, but I could not recover.
I decided after work to redo the website. There is still some missing news article, but everything from this year is there. I still have the old website working and I will slowly add them.
This was a humbling situation and a good reminder that I should never skip doing a backup, even if all previous upgrades did go as planned.
I am sorry for the inconvenience that this has caused.
