Reddhat 8.9 Apache issue with Mantis 2_26_2

[gerrymantis]

After running Mantis successfully for many years on version 2_10_0 on CentOS 6.10
with Apache 2.2, PHP 3.2 and MySql 5.7.1

I am trying to get Mantis Version 2_26_2 running on RedHat 8.9
with Apache 2.4, PHP 8.3 and MySQL , then import customizations and existing MySQL data.

But it has not gone well.
PHP8.3 info() request works, proving it works. The same with checks on MySql.
I turned on error log debug to see the challenges with trying to execute mantis,
and used the /admin utilities to check for errors, but did make the mistake of customizing
mantisbt files like the old version, like config_inc.php, first.

So, my plan is start over with no customizations with a mantis install out of the box.

However, before doing that,
I updated my httpd services, which has been updated httpd.conf and conf.d files to apache 2.4
i.e., removed/replaced deprecated LoadModules and permission access commands,

The systemctl start/restart http command just remains hung and never returns to the
command prompt.

Plus, journalctl -xe shows very little
webserver systemd[1]: home-userID.mount: Succeeded. Not sure why a userID (not mine is started with httpd
no error_log or access_log

I am lost. Can anyone share a sanitized (no personal/company ip addresses) of an httpd.conf file that works well
for mantisbt ? Note: the server is dedicated to mantisbt and no other applications.
