WordPress has a lot of moving parts: the database, the web server, WordPress itself, your content, your plugins, your theme… It can be confusing to figure out how it all fits together. In this talk, I will go over all of the working pieces in a standard self-hosted WordPress installation, including things like what the webhost does, what files are present and their role, and how WordPress uses the database. It’s helpful to understand how it all fits together so that you can track down problems on a site, make improvements to a site, or just have a handle on what happens under the hood when you use WordPress.
