[astarmathsandphysics]

I upgraded to from 19.04 to 20.04 at xmas, and that broke sll for all my websites.
I changed no setiings in apache2 or sll, saved the config files etc, spent more than a month trouble sghooting but no joy.
Am usncloudflare, and have reinstalled apache2, php7.4, openssll again,, going through to rewrite config giles with riginal settings, whiich worked for years.
Any ideas?
