error on ubuntu 14.04 (Deprecated: mysql_connect())

on the page http://*.*.46.4/ehcp/ write error:
"Deprecated: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in /var/www/new/ehcp/config/adodb/drivers/adodb-mysql.inc.php on line 370"

Why is this error, how to fix it? Please help me
