[FIX] Disable Subscription PopUp

1. Change to working directory

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'),

6. Restart the Proxmox web service (also be sure to clear your browser cache, depending on the browser you may need to open a new tab or restart the browser)

systemctl restart pveproxy.service

You can quickly check if the change has been made:

grep -n -B 1 'No valid sub' proxmoxlib.js
