When there is a list in the zabbix frontend, and I want to go to the second page, the url is not the hostname but just "localhost", which will not work. When I replace localhost with the correct name, it works.

zabbix url: http://localhost/triggers.php?groupid=24&hostid=10129&sid=bd4eb67a219479ba&page=2

correct url: http://zabbix.internebula.org/triggers.php?groupid=24&hostid=10129&sid=bd4eb67a219479ba&page=2

Maybe this is a config file I forget to change? Searched /etc/zabbix and subfolders for "localhost" already.
