Empty panel page

Hey, I just updated a (previously working) Kirby website, re-uploaded it to the server and now: everything works perfectly, only the /panel route is completely empty. Nothing gets loaded.

So I checked:

  • does it work locally (yes it does)
  • composer dump autoload, re and re upload it again
  • php version (8.1)
  • .htaccess rewriteBase (it’s set to ‘/’ because its hosted on Ionos)
  • delete everything on the server and reupload
  • file permissions (everything to 777)

Any ideas what I can try next?
Thank you for any ideas!

Okay, I got it now. My FTP program skipped the folder kirby/panel
