Warning: mysqli::__construct(): (HY000/2000): mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication.

If this user is used in other scripts executed by PHP 5.2 or earlier you might need to remove the old-passwords flag from your my.cnf file in /web3/photosferroviai/www/include/dblayer/functions_mysqli.inc.php on line 52
