Code has been updated adding an exemption to the css.php file which if not present causes the designers mode to display the site without css.

https://gist.github.com/zeronug/a16b06fde32dbf0685a5

# Allow access to CSS file
location ^~ /applications/core/interface/css/css.php {
        include /usr/local/nginx/conf/php.conf;
        allow  all;
}

Also added better code for protecting the real admin directory.

# Secure real admin directory
# Replace /your_admin_renamed_directory/ with your renamed directory.
location /your_admin_renamed_directory/ {
    auth_basic "Private";
    auth_basic_user_file /usr/local/nginx/conf/htpasswd_admin_php;
        include /usr/local/nginx/conf/php.conf;
        allow 127.0.0.1;
        allow YOURIPADDRESS;
        deny all;
}
