Hello,

No, it is a bone stock Heimdall image installation (lscr.io/linuxserver/heimdall:2.5.8). I just re-created the issue on a stock rpi install and fresh pull below, without the page loaded.

The /docker/heimdall/config bind volume in the docker-compose.yml files above is an empty directory upon creation of the first container, as well as the second run against :latest, which is still actually lscr.io/linuxserver/heimdall:2.5.8; just checking if there had been any changes, but it appears the behavior is still present.

I've also just now separately recreated on a quickly spun-up ubuntu-22.04.4-LTS amd64 proxmox VM with lscr.io/linuxserver/heimdall:2.5.8 to rule out (unlikely) differences between architectures or host configs; same behavior with the php daemon reading the /docker/heimdall/config/www/app.sqlite every 3 seconds:
