Thanks to everyone for their help on this. Its been some days but only had time to fix it all up now.
Big shout out to Hannah though for taking the time to outline such a detailed response. That sort of support for a self hosted blog was not expected. I guess that is the result of passion for the product, and well due as well. Ghost is just amazing.
I went with Hannahs route and it worked perfectly. My url even if entered with the www directs as a 301 right over to the https://tidy… url
In future any ghost setups I carry out now I feel confident in making sure their is a uniform address format welcome regardless of which way the site is visited or indexed via search engines.
Been a real pleasure. Many thanks again and hope every one is safe and well.
