12.0 -> 15.0 upgrade. Files issue.
Hello !
I'm doing a test upgrade with xampp on my laptop before doing the deed on our website (permaculture.alsace).
Everything seems ok but I have a problem with the files.
I copied the content of /www/files/ from my backup to the new /www/files/ folder but when I download a file it's not possible to open it.
Did I miss something in the upgrade process ?
