web gui blank after removing postfix

[Johntaa]

Hello, I decided to remove postfix from proxmox unit because I have Installed postfix on a VM that will be dedicated to mail services. but lost proxmox web user interface and it returns a blank page, with https status

" 501 file error - /usr/share/pve-manager/index.html.tpl: not found".
but the folder pve-manager is not exist

all log files contain no error (at least the files I suspect it relate to proxmox)
Can anyone assist me to solve this issue ?

I noticed that the folder /etc/pve is empty No files there , also lost the commands , all pve commands return "Command not find"
this is a single proxmox node not a cluster

Ok,Problem Solved , for anyone having the same issue :
Uninstalling Postfix will remove pve-manager components
So:
sudo apt-get install pve-manager
will restore everything .
