"This seems like something messed with your JavaScript, are you sure you did not install some customizations, like something removing the subscription reminder pop-up? In that case you'll have to complain to the author of that customization."

From Which version? When the PVE-Post-Install was executed?

PVE manager was updated from 8.4.4 to 8.4.5, unfortunately i can´t tell you when the last time the "post-install script" was executed, ibut definitely before version 8.4 of PVE

We have an updated variant of this - but your error is completly unknown to me.

try this:

rm /etc/apt/apt.conf.d/no-nag-script
apt reinstall pve-manager
apt reinstall proxmox-widget-toolkit

Didn´t worked BUT
i installed a fresh PVE version in a VM, upgraded to 8.4.5 and copied the files from the VM to the non-working cluster member.
No its working ...

It seems that something prevented overriding of the old 8.4.4 files (the files had different sizes and creation dates)

im wondering about this issue:
Failed to load resource: the server responded with a status of 500 (no such file '/PVE/StdWorkspace.js')

This is definitely not from us, have you run any other 0815 Github scripts in the past?

I can't rule it out, at least I don't remember and my console history shows , that i didn´t used a script of that kind in the last 6 month (then the history is truncated)
