After 4.0 Upgrade - Some Pages not working: Integration, Trigger, Webhook

  • Used Zammad version: 4.0
  • Used Zammad installation type: (source, package, docker-compose, …)Installed from packed
  • Operating system: Debian 10
  • Browser + version: Edge + Firefox + Safari (newest)

We’re in the preparation of implementing Zammad, only some tests done. Before going live I did a Update from Version 3.6 to 4.0 through apt-get upgrade.
Now when I’m in the admin part I have this problems.

The page Integration is completly empty. In apache logs I can see the Integration link with http 200 code.

Additionally the page Trigger and Webhook. I see a animated green Icon Loading… (german: Laden…)

Update installed on Friday to 4.0.
Another 4.0 Patch was available on Sunday.
Some reboots.
