Disabling the 'No valid subscription' warning in Proxmox VE 9

2026-08-03 Doğukan Meral

The Proxmox team has passive-aggressively stated multiple times that the easiest way is to support the project by purchasing a subscription (+ what else would you expect them to say, should they explain how to disable it?): See.

In this post, I will explain how to take the hard route and disable the ‘No valid subscription’ warning on Proxmox VE 9, which is licensed under AGPLv3.

Back up the JS code on the Proxmox server:

cp /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js.backup

Make the relevant changes to the JS code:
