916	Incorrect map value passed.	plutocrat@…		"Hi,
I'm running a Wordpress Multisite instance, and have used the suggested mapping scheme in it. Mine looks like this.

{{{
map $http_host $blogid {
        default 2;
        domain1.com 1;
        temp2.domain1.com 2;
        domain2.com 2;
        temp3.domain1.com 3;
        domain3.com 3;
	.... etc ....
        temp11.domain1.com 11;
        domain11.com 11;
        .... etc ....
        temp17.domain1.com 17;
        domain17.com 17;
}
}}}

Later on in the config, I use it like this:

{{{
location ~ ^/wp-content/uploads/(.*)$ {
        try_files /wp-content/uploads/sites/$blogid/$1 /wp-content/uploads/$1  /wp-includes/ms-files.php?file=$1 ;
        access_log off; log_not_found off; expires max;
}
}}}
This was previously working OK: If the file
domain3.com/wp-content/uploads/2014/12/test.pdf
was requested, then the file from 
domain3.com/wp-content/uploads/sites/3/2014/12/test.pdf
would be served

I was experiencing problems with this on one site, domain11.com. I turned on debugging in the logs and found that it actually seemed to be mapping domain11.com to $blogid=1 instead of blogid=11.

So is this a bug, or have I just misunderstood the map format? Is there a workaround?
I tried uncommenting the other $blogid=11 (ie. temp11.domain1.com). That didn't fix it. 
I tried putting """" around the value 11 in the map. That didn't fix it.
