The plugin no longer works in the latest stable version of WHMCS V8.12.1 and PHP 8.2, ionCube 13.3.1 HELP !!!..

The plugin has stopped working.
I made the mistake of updating my WHMCS
to version:
whmcs V8.12.1
PHP 8.2
ionCube Loader: 13.3.1

Error: Undefined constant "sortx" in /home/esalhost/cliente/modules/addons/StormBilling/pages/configuration/configuration.php:21
Stack trace:
#0 /home/esalhost/cliente/modules/addons/StormBilling/core/core.php(157): require()
#1 /home/esalhost/cliente/modules/addons/StormBilling/core/output.php(3): require_once('/home/esalhost/...')
#2 /home/esalhost/cliente/modules/addons/StormBilling/StormBilling.php(85): require_once('/home/esalhost/...')
#3 /home/esalhost/cliente/esalhost/addonmodules.php(0): StormBilling_output(Array)
#4 {main}

Would it be possible to update it so that it works correctly and we can continue adding servers?

Start with modules/addons/StormBilling/pages/configuration/configuration.php at line 21, then follow the stack trace through core/core.php, core/output.php, and StormBilling.php. Reproduce the configuration-page failure under WHMCS V8.12.1, PHP 8.2, and ionCube Loader 13.3.1; done means the page loads without the reported error and servers can be added.
