Upgrade Process

WHMCS 8.0 and above requires PHP 7.2 or later. WHMCS 8.0 introduces support for PHP 7.4. Earlier versions of WHMCS do not support PHP 7.4.

You will only see the WHMCS 8 updates within the Automatic Updater if you are running on PHP 7.2 or later. If you are running PHP 7.1 or earlier, to update to WHMCS 8 via the Automatic Updater, you will first need to upgrade to PHP 7.2 or PHP 7.3, and then check for updates and perform the update.

Once you are running WHMCS 8, you can upgrade to PHP 7.4.

Automatic Updating

If you are running WHMCS 7.0 or later, you can use the built-in Automatic Update utility.

Go to Utilities > Update WHMCS to begin the process.

If the update was released recently, you may need to click Check for Updates before the update will be available.

For more information about updating, refer to the Automatic Updater documentation.

Affiliate Commission Reversals

New updates to the affiliate system help you reverse commission payments for disputed or refunded purchases. This ensures that affiliates won't receive a commission if your business did not retain the funds from a given purchase.

Improved SSL Certificate Validation

WHMCS now supports DNS validation for MarketConnect's DigiCert SSL certificates. Starting in October 2021, wildcard certificates no longer allow file based authentication and require validation using either DNS or email. Our changes include interface improvements that allow clients and admins to access validation data for certificates that are waiting to be issued.
