ISPConfig Uncaught Error: Class 'auth' not found

Hello together,
I'm currently facing this problem: If I'm trying to access the web admin of my ISPConfig instance just a white site occurs. In the apache2 error log following error is logged:

Code:

[Thu Oct 27 14:35:55.129877 2022] [fcgid:warn] [pid 3567859] [client  :14470] mod_fcgid: stderr: PHP Fatal error:  Uncaught Error: Class 'auth' not found in /usr/local/ispconfig/interface/lib/app.inc.php:154

I compared the app.inc.php with the official one and they are equal.
Has anyone an idea what is the cause of the issue and how to solve it?

Thanks in advance

Hi Till,
here you go:

Code:

[14:57:45] root@ubuntu ~ $ php --version
PHP 7.4.27 (cli) (built: Dec 20 2021 21:27:56) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
    with Zend OPcache v7.4.27, Copyright (c), by Zend Technologies

Okay, I will try to use the update option.

 

Your PHP Version seems fine but migth consider updating the system anyways the current build for debian is 7.4.30 is from Jul 7 2022.


Did the update work?

 

Yeah, the update did work. Thanks
