Resolved LightSpeed - FPM application served by Apache uses wrong PHP Version

[yogi70]

Server operating system version

AlmaLinux 8.7 (Stone Smilodon)

Plesk version and microupdate number

Plesk Obsidian Web Pro Edition 18.0.50 Update #2

Symptom: when I change the PHP-FPM version on a subdomain from 7.2.34 to 7.4.33 the hosting still uses the 7.2.34 system. Looks like this happens to all Domains / Subdomains when selecting "FPM Application served by Apache"

I also found this thread Resolved - PHP FPM stuck on OS vendor version but could not find what was done there to solve the issue.
Also my system is not using the OS-Version of PHP - that is 7.2.24

the Domain config is listed in /opt/plesk/php/7.4/etc/php-fpm.d/ and contains
also the apache config file /var/www/vhosts/system/<domainname>/conf/httpd.conf looks fine for me:

<Directory /var/www/vhosts/<domainname>/shopadmin-dev/public>

                        <IfModule mod_fcgid.c>
                                <Files ~ (\.fcgi$)>
                                        SetHandler fcgid-script
                                        Options +ExecCGI
                                </Files>
                        </IfModule>
                        <IfModule mod_proxy_fcgi.c>
                                <Files ~ (\.php$)>
                                        SetHandler proxy:unix:/var/www/vhosts/system/<domainname>/php-fpm.sock|fcgi://127.0.0.1:9000
                                </Files>
                        </IfModule>

                        SSLRequireSSL

                        Options +Includes +ExecCGI

                </Directory>

If I change from fpm to fastcgi the config file is changed and I get the correct version reported by phpinfo().

The Socket used by the Apache Config is bound to the correkt php-fpm process:

I now found this Article:

Unable to change the PHP settings when using LiteSpeed Web Server with Plesk - Support Cases from Plesk Knowledge Base

Unable to change the PHP settings when using LiteSpeed Web Server with Plesk - Support Cases - Plesk Knowledge Base

www.plesk.com

which explains that liteSpeed is not working with APACHE PHP-FPM
