How to Remove Proxmox Subscription Warning on Proxmox 9.2.2

After installing Proxmox VE, most of users will see the “No Subscription” popup in the web interface.

While it does not affect system functionality, it can be annoying. Here is how to disable this message cleanly and safely

Modifying the JavaScript File

Open your Proxmox web console or connect via SSH as root.
Go to the widget toolkit folder:
cd /usr/share/javascript/proxmox-widget-toolkit
Make a backup copy of the original file:
cp proxmoxlib.js proxmoxlib.js.bak
Open the file using a text editor like nano:
nano proxmoxlib.js
Search for the subscription check line containing data.status.toLowerCase() !== 'active'.





Change !== to === so the line reads data.status.toLowerCase() === 'active'.



Save the file by pressing Ctrl + O then Enter, and exit using Ctrl + X. 

Restarting Services and Clearing Cache

Restart the Proxmox proxy service to apply changes:
systemctl restart pveproxy.service
Clear your browser cache or open a private/incognito window before reloading your Proxmox web UI.

Is it legal and advisable for production?

Proxmox VE is free software under the AGPLv3. Using the no-subscription repository on your own server is entirely permitted. You do not buy a subscription for the right to use the software, but for access to the tested enterprise repository and vendor support.
