Nagios is one of those apps that just works all the time so I don't spend much time under the hood looking. Because of that I really don't have any idea where to start troubleshooting. I came in this morning - tried to log into the application and received this when going to the login screen.

I added index.php to the httpd.conf file (has I have seen others do)

Code: Select all

<IfModule dir_module>
    DirectoryIndex index.html index.php
</IfModule>
Now I can at least see the
Welcome
Click the link below to get started using Nagios XI.
Access Nagios XI (blue button)

But when I click it I get the following

Code: Select all

<?php

require_once(dirname(__FILE__) . '/includes/common.inc.php');

init_session();

// Grab GET or POST variables and check pre-reqs
grab_request_vars();
check_prereqs();


route_request_main();


function route_request_main()
{
    $default_page = PAGE_HOME;

    if (is_authenticated() == false) {

    display_page($page);
