访问脚本'xxx/xxx/php'已被拒绝(请参阅security.limit_extensions)

我得到了这个错误。显然，我想使用ckfinder来上传文件。

Access to the script '/var/www/example.com/public/admin/scripts/vendor/ckfinder
/core/connector/php' has been denied (see security.limit_extensions) while reading 
response header from upstream, client: x.x.x.x, server: 
example.com, request: "GET /admin/scripts/vendor/ckfinder/core/
connector/php/connector.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", 
host: "example.com"

我已经将security.limit_extensions设置为。php。我看过访问拒绝(403)的PHP文件与Nginx + PHP- fpm，我尝试了他们中的大多数(除了fix_pathinfo)没有运气。在我注意到错误消息中的脚本路径之前，来自connector.php的GET请求位于php/目录中。我认为问题是nginx看到这个目录名称作为脚本，并试图运行它，不确定。

这是我的nginx服务器块。

        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param LARA_ENV local; # Environment variable for Laravel
        fastcgi_param HTTPS off;
    }
    location ~ '.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+.php)(/.+)$;
        # With php5-fpm:
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param LARA_ENV local; # Environment variable for Laravel
        fastcgi_param HTTPS off;
    }
    # Deny .htaccess file access
    location ~ /'.ht {
        deny all;
    }
}

我的问题是如何指示nginx知道php/是一个路径，而不是一个脚本?
