WHMCS is a popular web hosting management and billing software that automates many aspects of a web hosting business. However, there might be instances where you need to uninstall WHMCS, either for troubleshooting purposes or because you’ve decided to use a different solution.

In this guide, we’ll walk you through the steps to uninstall WHMCS from an Ubuntu server.

Let’s get started.

Step 1: Backup Your Data

Before making any changes, it’s crucial to backup your WHMCS data. This ensures that you can restore your data if needed.

  • Log in to your WHMCS admin panel.
  • Navigate to Utilities > Database Backup.
  • Follow the on-screen instructions to backup your database.

Step 2: Remove WHMCS Files

Access your server via SSH and navigate to the directory where WHMCS is installed. Typically, this might be /var/www/html/WHMCS or a similar path.
