Update the System URL

To ensure that your WHMCS installation can function, your system URL setting must be correct at all times. Additionally, some features require you to enable SSL and use the https protocol in your system URL.

After moving a WHMCS installation you must update WHMCS System URL to reflect the new location.

Update the System URL Setting

To update your system URL:

  1. Go to Configuration () > System Settings > General Settings.

  2. Choose the General tab.
    The General Tab

  3. Enter the correct URL in WHMCS System URL.
    The WHMCS System URL Setting
    For example, if example.com uses an SSL certificate and the WHMCS installation is in the whmcs directory, the system URL would be:


    In this case, starting the URL with http://, omitting the www, or other deviations could cause errors. The system URL must match exactly.

  4. Click Save Changes.

Enable SSL

WHMCS often contains private and sensitive data that passes between WHMCS and end users’ browsers. Having a valid SSL certificate that enables the use of HTTPS and encrypted communication is essential for data security.

We recommend performing this task and other security measures immediately after installing WHMCS. For a full list of recommendations, see More Ways to Secure Your WHMCS Installation.

To enable SSL on your WHMCS installation:

  1. If you do not have an SSL certificate, purchase one.
  2. Configure the SSL certificate on the domain that hosts WHMCS. The method to use will depend on the hosting control panel that you use.
  3. Update the WHMCS System URL setting using the steps above, entering your website’s https://-enabled URL.
  4. Click Save Changes.
