Hi,

I’m trying to run dokuwiki with https.

On the nginx-wiki there is a doku about this:

> **[Dokuwiki | NGINX](https://www.nginx.com/resources/wiki/start/topics/recipes/dokuwiki/)**
>
> A sample NGINX configuration for Dokuwiki.

Problem: When including "fastcgi\_param HTTPS $php\_https; there is this  
error while reloading nginx:

Reloading nginx configuration: nginx: [emerg] unknown “php\_https”  
variable

Any idea, why this happend?

Thanks allot  
Chris

Probably because you’ve not defined it in a map directive like this at  
the http level.

map $scheme $php\_https {  
default off;  
https on;  
}
