I haven’t posted much recently as I have started a new job. Hopefully in the next few weeks I will remedy this.
I have just moved the website from a Pi zero to a Pi 4. Took most of a whole Sunday to do it. The Pi zero was becoming slow and WordPress was complaining about an insecure version of PHP. I will also look at running it off a SSD for reliability and speed. I will add instructions for this in due course.
