Hello,
I wonder if someone managed to run qloapps with let's encrypt. The install page doesnt show . Certificates have been installed before, just to make sure that ssl work. To summarize.

• Installation of Apache, PHP and MySQL works for http and https. I can access the default apache or php page
  .- when i copy the hotelcommerce folder to the root folder of apache , i can't access the install page via https or http. I blank page appears with no error at all.
  Any idea ?
