Problem installing ModX Revolution - Help

Installed clean system according to the instructions - www.howtoforge.com/tutorial/perfect-server-debian-9-stretch-apache-bind-dovecot-ispconfig-3-1/
Created a client.
Created a website (PHP-FPM).
Created a DNS zone.
Created database and user.
Created an FTP user.
Downloaded archive with the latest version of ModX Revolution 2.6.3, unzipped and uploaded via ftp to the folder " web " on the server. When clicking on the link domain.com/setup/ writes:
"FATAL ERROR: MODX Setup cannot continue. Make sure your PHP session configuration is valid and working."
As far as it became clear, modx revo need a folder "mod-tmp" to store cookies, but I can not add it via ftp, ssh, too.
Just uploaded wordpress instead of modx, everything works fine, no problems with PHP session configuration.
1. Question, how to solve this problem ?
2. Can I make changes to the ISPConfig 3 site creation wizard to create not only the tmp folder but also the mod-tmp folder ?
Where can I make these changes ?

 

Make sure your configuration is valid ... https://docs.modx.com/revolution/2....ettings/system-settings/session_handler_class

try the database handler or check the code for the default handler for bugs or hard-coded stuff to be able to change the directory for instance.

Code:

<?php session_start();
$_SESSION['foo'][] = time();
var_dump($_SESSION['foo']);

quick test.php, it should output more and more every visit, if sessions in general are working.

Did you use mod_php, fastcgi or php-fpm?
