Wordpress Multisite and nginx in a subdirectory

Okay, we’re trying to wrap our heads around a WP config situation in the
WP support forum:


Just curious if anyone here has faced the same issue.

  • WP is installed in /blogs. Additional blogs are to be /blogs/blog1,
  • WP multisite is activated
  • while main site in /blogs works fine under nginx with this
    location(*), network admin links and the multisite database thinks the
    site is suddenly in root instead of /blogs

I’m not exactly sure why the WP support thinks nginx might be causing
this issue, unless WP is somehow getting some environment variable when
it installs network support. As far as I understand, I know nginx can
rewrite locations, but it wouldn’t pass an environment along would it?

So I guess my big question is: is anyone here running WP multisite in a
directory? Did you have the same issue with some admin links pointing to
root? Should I tell WP support that nginx couldn’t be causing this?

Could it possibly be caused by WP’s php getting some variable from

WP support’s been scratching their heads for about two weeks.

  • here’s the location:

location ^~ /blogs {
try_files $uri /blogs/index.php?q=$uri;
location ~ .php$ {


fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;

As I think about this…I’m wondering if it might be the fastcgi.
