Cron PHP Version Mismatch

[Fabio Perez]

I recently upgrade the OS on the WHMCS server from Debian 11 to 12.

 

This change also upgraded the PHP version from 8.1 to 8.4.

Now on my WHMCS dashboard I see this warning

Cron PHP Version Mismatch
Your environment appears to be running a different PHP version (8.1.30) for the System Cron than the currently loaded PHP version (8.4.14). This may cause issues running your System Cron

Just to be sure, I removed all old PHP versions from the server, so there is no php8.1 anywhere on the server.
Then, reading some docs, I saw that WHMCS only support php8.3. So I installed that version.

If I ran `php -v` on my server I get
```
php -v
PHP 8.3.27 (cli) (built: Nov 13 2025 21:19:55) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.3.27, Copyright (c) Zend Technologies
    with the ionCube PHP Loader v15.0.0, Copyright (c) 2002-2025, by ionCube Ltd.
```
I also using `fpm` on my nginx config file like this `fastcgi_pass unix:/run/php/php8.3-fpm.sock;`

Still I have this warning that Im not sure how to get rid of. And now the Daily Cron Completing fails.

Any help would be much appreciated it.

Thanks.
