WHMCS Update & ionCube Compatibility Issue

Job ID: 40478728

Budget: ₹600 – ₹1,500 INR

I am facing an issue while updating WHMCS on my server.

Error:

The file /home/amzsrvr/public_html/cart/vendor/whmcs/whmcs-foundation/lib/Installer/Composer/Hooks/ComposerInstallerHook.php has been encoded by the ionCube Encoder for PHP 7.1. PHP Fatal error: Only files produced by the PHP 8.2 ionCube Encoder can run on PHP 8.2.

Additional Details:

WHMCS update fails during the upgrade process.
Server is currently running PHP 8.2.
The update process stops with a fatal ionCube compatibility error.
Error suggests the existing WHMCS files are encoded for PHP 7.1 while the server environment is attempting to run them under PHP 8.2.

WHMCS displays:

Update Failed

An error occurred that prevented the update from completing successfully.

A fatal error occurred while fetching the update.
