General Troubleshooting

General errors can occur in many places throughout WHMCS, and can be due to many different problems. However, fixing them is often simple.

Install WHMCS

The first step to using WHMCS is installing it on your server. WHMCS includes an easy browser installation tool to suit most users' needs.

Troubleshooting Installation

When you install WHMCS on a server, make sure to watch for errors both during and after the installation process.

Install on the Command Line

If you want more configuration options than browser-based installation offers, you can install and upgrade WHMCS on the command line.

System Requirements

For successful installation, updates, and operation, your system must meet the minimum system requirements for your WHMCS version.

Updating WHMCS

You can check for updates and apply them directly in the Admin Area.
