Hello everyone, I try and try back up an LXC VM but keep giving me an error:

The VM is located on an NFS share.


In addition, the email summary screen seems unformatted

i can Reproduce the issue (at least in my VM)
I dont think its the PBS, i think its related to the PVE

PVE was on 6, Problem exist since
PVE war 6 bei mir, Problem existiert seit PVE 7 / PBS 2

Current version PVE 7.1-10 PBS 2.1-5

Ich kann den Fehler so Reproduzieren (zumindest in meiner VM)
Dies aber nicht nur auf dem PBS sondern auch nur auf dem PVE daher denke ich ist das Thema eher in PVE anzusiedeln.

PVE war 6 bei mir, Problem existiert seit PVE 7 / PBS 2

Aktuelle Version PVE 7.1-10 PBS 2.1-5
