Gallery pages 404 after upgrade

I’ve upgraded to Sunshine 3 (the regeneration of images still runs), and most things seems to work and look good, but all gallery pages return 404. The main gallery page loads well, but when selecting a gallery you’ll get a 404.

It doesn’t matter if i use the new url pattern (ie: https://jestaaterop.nl/album/apenheul/) or the old url, that gets redirected (ie: https://jestaaterop.nl/albums/album/apenheul/)

The page I need help with: [log in to see the link]
