cd /usr/share/javascript/proxmox-widget-toolkit

2. Make a backup

cp proxmoxlib.js proxmoxlib.js.bak

3. Edit the file

nano proxmoxlib.js

4. Locate the following code
(Use ctrl+w in nano and search for “No valid subscription”)

Ext.Msg.show({
title: gettext('No valid subscription'),

5. Replace “Ext.Msg.show” with “void”

void({ //Ext.Msg.show({
title: gettext('No valid subscription'),
