Recently I moved my WHMCS installation to a new AlmaLinux 9 server. Before copying my existing install over and moving my database over, I had installed Apache 2.4, PHP 8.1, MariaDB 10.11 and Memcached for PHP Sessions.
I spent a big chunk of time trying to troubleshoot why WHMCS said session weren't working (said it couldn't write to the directory tcp://localhost:11211) .
It did seem to work, but to get rid of the error, I switched PHP Sessions back to
I would like to see support for memcache/d for the session handler as my eventual goal is to containerize my WHMCS installation, with having the ability to use a Memcached container as my session host.
