I have the old (oulde?)13/03A version. I made my own template/css changes for css/html5 and then the SSL/TLS changes. It seems to be working OK up to PHP7 but now I see that other things (like WP) are asking for upgrades to PHP 7.4 and I thought before I click that change I should stop in and see whether that might not be a good idea with my PT sites. It seems that I am a few steps behind.
From looking at the changelog it seems I should think about upgrading. Because my templates and css are just fine but will need to be adapted I suppose, I am here to ask for your suggestion of whether I should be trying with 16/10A or go to 18/06A for an easier transition?
I migrated to better server conditions a few years ago and have been very happy with performance - but I do know I can't live in the past and need to make some adjustments and have put off this step because it seems that it could be like starting over.
Help? Do I just dive in and overwrite my old install or is it better to set it up in private and then move it online?
Thank you again for an immensely useful set of tools.
