@sharif My host release is "Red Hat Enterprise Linux release 8.8 (Ootpa)"The upgrade that broke the install was: Upgrade carbonio-webui-4.0.27-...

Upgrading to 23.10 doesn't fix the issue.Admin UI on RHEL8 is still unusable.

Same issue here with "Red Hat Enterprise Linux release 8.8 (Ootpa)".I think it might be related to RedHat OS. Thanks Giovanni
