First, thank you for such fast return.
I’m happy to learn that you think it is not a Hype issue.
This morning, it been found out that everything work fine… while the browser (Safari, Chrome) is in “Private Mode”!
So, my PHPs code seem to be OK, if it work while private.
I’ll investigate toward the Certificate; keep you posted.
Thank you again! (Your answer gives me a super boost!)
