That worked fine however 2 wordpress sites which are in subdirectories of that domain, were not running in https mode.
I modified one of the wordpress sites notjust4u/demo3
to run in it in https mode following instructions in: https://reviewofweb.com/how-to/migrate-wordpress-from-http-to-https/
and was troubleshooting to figure out why it wasn’t
Figuring that there may have been a glitch (CONFESSION: I did make some cosmetic changed to vhosts-le-ssl.conf, indenting some of the directives to align with the rest of the file), Maybe that messed things up.
I edited vhosts-le-ssl.conf fo fix things. Well that only made things worse.
Is there a clean and easy way to purge|delete|erase all my letsencrypt certificates and infrastructure changes, so I can
start all over again?
