Restored this blog to the internet. This basically involved:
Upgrading all the wordpress plugins and wordpress using the wp cli command
Importing an old XML copy of the blog exported from WordPress
Using Akismet to filter out all the spam comments
Taking the list of missing images and then replacing them by downloading the image from the Wayback Machine from the Internet Archive.
Working out how to use Blocks and all the other changes to WordPress since last I used it to actually write content.
