But to be fair, the authors core point is correct - running Wordpress locally and then deploying to the internet is an absolute tire-fire.

For context my wife uses wordpress to build various sites. I got lumped with the task of moving this online. It was super painful, as WP encodes the URL name (i.e. localhost) flipping everywhere.

I eventually resolved this by editing the tables which stored the URLS (fortunately, as a DS I know SQL) and doing some sed on various files that cached the URL.

I now refuse to do this, and set her up online with a website before she does any work, because moving it is so painful.
