On Nginx, when I choose “Disable Virtual Server”; it does disable at least the database, however, the actual website still works normally (if it doesn’t use MySQL/MariaDB).
Try testing it by placing Hello World in the domain document root inside the index.html file before disabling it, and see if it actually gets disabled or if the wrong site just shows up.
Thank you, I just tried another your suggestion with another virtual server. Everything gets “locked” but the website stays up as normal. This particular one is a simple site, no php, just an index.html file.
