So clearly making posts on Staging works. But of course if I make a post on the live site directly it is going to get overwritten and lost. So that means there has to be a process when making a change:
Make a taging copy of the live site.
Make edits and test.
Push to live.
I also need to check what happens about other changes e.g.
Changing versions of plugins
Changing versions of themes / different theme.
Adding a plugin.
Adding a page.
Editing a page.
Adding media to the media library.
If that all works then just maybe we have a working process!
As part of my ongoing education with WordPress as a web platform I have been experimenting with automatically posting from the website to Facebook and Twitter with a plugin called SNAP. This the first test!
