I have error during or right after installation of Siremis

Question

I have a server running a clean install of Ubuntu server 22.04 with apache2.4.52, php7.4.29, kamailio 5.5.4, and Siremis 5.3.0. After finally working through all the errors and removed depreciated code, there seems to be nowhere to go once logged in. Page redirects to systemip/Siremis/system/general_default but the returns Not Found. The requested url was not found on this server. I have been through so many issues with this installation. First I had to downgrade PHP version since kamailio/Siremis does not work with php8(only gives blank page.), Then locate and install all php7.4 dependencies,including pdo_mysql and phpxml. After finally getting to the database installation had to fix many write permissions, and comment out Function get_magic_quotes_gpc() from clientproxy.php before install would complete. So all tables and databases seem to be configured correctly but now that installation is complete I am redirected to myip/Siremis/system/general_default with error url not found on this server.

So far I have tried to uncomment the magic function and switched to php7.3. Right now apache error log says unable to load the php_pdo_mysql.so file that I have verified is in the path identified in phpinfo(). Also PHP -i and PHP -m show pdo enabled and version 8.1. This has been one problem after another for several days now.
