After another update during October 2021 both (a) blocking me from posting updates and (b) taking out all the posts made after 2018 and most of the stored graphics library, I left the website and blog side dormant as I was very busy in other areas.
This is an attempt to restore what I can of the lost posts from Internet Wayback archive copies and finally crack the problem of why the change to Block Editing in WordPress seems to be causing these problems. It has been identified as that as re-loading the older Classic Editor has facilitated this update.
Therefore my apologies to anyone who has recently visited and seen the corrupted site home page (It changed the installed theme).
