This was tested in 3.22.x and needs to be retested in newer versions of Koha. When accessing administration > audio alerts, an 'internal server error' is shown with Plack running.
I do not recreate, what is the error?
I don't have server access there to check for the exact error. Did you check on master or latest 3.22.x?

Hm, odd. Thx for checking!
Works fine for me on current master. No error.
Closing, please reopen if it persists.
