Before Start

  1. Plese make sure that theme version, which you are trying to install is compatible with your WHMCS installation!

  2. We suggest testing our template on your environment, before activating it for all your clients. Each environment is different, so some problems may occur. You can preview your installed theme by clicking the below marked button in our addon.

Upload Files

  1. Download latest theme release and extract downloaded zip file.

  2. In the extracted folder you will find two packages that support different PHP versions
