Updated and noticed package-manager was missing all settings so checked this post and see I have to remove package-manager to install extension manager which I have now done.
Sadly however I cannot enable Extension Manager - seems to generate a 500 error on POST to /api/extensions/flarum-extension-manager
The browser console
