Internal Server Error on Fresh Installation

[dwp]

Hi,

I have installed Nagios 3.5.0. on Ubuntu Server 12.04 correctly,
using the instructions on this link: http://nagios.sourceforge.net/docs/3_0/ ... buntu.html

I can enter at Home of Nagios perfectly after installation,
but... if I do click on links of left-menu (For example, sections like 'Tactical Overview'), the Nagios page says:

---
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator to inform of the time the error occurred and of anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
---

NOTE1:
with command:
# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
Nagios says -- 0 ERRORS --

NOTE2:
Selinux is disabled

NOTE3:
The htpasswd.users are created correctly

¿Possible Solutions Please? :S

Thanks in advance!

Bye,

Is the nagios process running?

Code: Select all

service nagios status

Have you configured cgi authentication?

Can you post the nagios.conf file? I believe in Ubuntu should be in "/etc/apache2/conf.d/".

Your config looks great! Lets check permissions on the the cgi files and such then.

Code: Select all

ll /usr/local/nagios/sbin
ll /usr/local/nagios/share
