Nagios Support Forum

Hi guys,

I've just installed Nagios according to this guide http://nagios.sourceforge.net/docs/3_0/ ... buntu.html following all the instructions, last step when accessing the web interface just spits out an error 500:

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Apache/2.2.8 (Ubuntu) Server at 192.168.111.167 Port 80

I've already rechecked all configutarion, step by step, I cant find anything wrong.

checking the logs I found this:

Could anyone give me some help please?

Regards,

never mind, followed another guide found here in the forum that did the job. Something on the sourceforge manual is not right

Would you mind linking the guide that worked for you? It would help us fix any innaccuracies in the official manual. Anyway, it's good to see you were able to resolve your issue.
