Error abour undefined index and variables after install

[sebelk]

Show me these warnings:

* Undefined index: DB[/usr/local/share/zabbix/include/setup.inc.php:678]

(That is: $old_DB = $DB['DB']

* Undefined variable: ZBX_SERVER[/usr/local/share/zabbix/include/setup.inc.php:685]

$old_ZBX_SERVER = $ZBX_SERVER;

* Undefined variable: ZBX_SERVER_PORT[/usr/local/share/zabbix/include/setup.inc.php:686]

(That is: $old_ZBX_SERVER_PORT = $ZBX_SERVER_PORT

Did it check if there was an older installation, it's not an error, is it?

Thanks in advance
