Cpanel 104.0.4 crashed WHMCS Admin Login

[garybarr 7]

2 hours ago, my Cpanel server auto-updated to version 104.0.4 and it kicked me out to a login screen.  I can enter my info, but it just goes back to the same screen, no errors, no password mistake.... Just the exact same screen without my info.  Our co-workers tried on theirs, different browsers, but no luck.  I've been working with Hostgator support for 3 hours now, but no luck on finding the issue.

WHMCS IS working until someone logs in.   On the user side, it gives a Invalid CSRF Protection Token error.

Anyone else run into this or have an idea on how to fix it?

Cambia el almacenamiento de las sesiones a base de datos con esto $session_handling = 'database'; con eso logre ingresar.

Hi all,
This behaviour suggests a problem with PHP session file storage on your server.

Attached is a simple script to test PHP sessions on your environment. Please unzip and upload to your public_html directory and visit in your browser.

Every time you refresh the page, the number should increase 1,2,3,4 etc...
However if the number stays at 1 on your server, this means there is a problem with the PHP sessions configuration that your server admin/hosting provider will need to investigate and resolve.
