Updating the Webserver to Ubuntu 24.04

I upgraded my webserver to Ubuntu 24.04 LTS recently and ran into an odd little issue. Apache2 refused to start up due to a PHP plugin failing to load. This was specifically PHP 8.1 failing to load as it was replaced in the repos with 8.3. This ended up having a quick fix to get things in order.

All I needed to do was disable the old PHP mod and enable the new one. I used this reference for which versions would be supported in 24.04 to enable the correct version. Overall a nice quick fix and my webserver was back operational

> sudo a2dismod php8.1
> sudo systemctl restart apache2
> sudo a2enmod php8.3
> sudo systemctl restart apache2

Apache/PHP Update

Back when I setup my webserver to run wordpress and dokuwiki, all the guides that I found and the guides that I followed had apache get setup with mod_php. However, after seeing this ArsTechnica WordPress Writeup, I realized that this might not have been the best way to get things going. I decided that this would be a good time to upgrade some of my webserver, so I started working on it, while my server was already setup, and the guide was on setting up a new server, the process is nearly identical, the only differences is that I had to disable/enable modules in a certain order for everything to work.
