Latest installation of UNA 11.0 cannot update member picture

I just did a fresh installation of UNA 11.0.  

Trying to create a personal profile for the default administrator

I found I cannot upload profile pictures.  

Please advise Is there anything that I may have done wrong?

It's a fresh installation.

using Nginx with UNA specific rules

        location / {

            index index.html index.htm index.php;

            rewrite "^/page/(.*)$" /page.php?i=$1 last;

            rewrite "^/m/(.*)$" /modules/index.php?r=$1 last;

            rewrite "^/s/([a-zA-Z0-9_]+)/([a-zA-Z0-9\.]+)" /storage.php?o=$1&f=$2 last;

            if (!-e $request_filename ) {

                rewrite  ^/(.+)$  /r.php?_q=$1  last;

                break;

            }

         }

        #end of UNA rewrite rules
