I use ISPConfig 3.1 and nginx 1.11.13. I found out, that if I choose any of the "Web server config" options here: Then the nginx directives that I specify on the "Options" tab are not applied at all: If I deactivate the "Web server config" option, then "nginx directives" are applied. From my point of view, "nginx directives" should always be applied. Is it true or not? Thank you in advance!
