Problem with rewrite and page not found.

Involves PNP4Nagios and me pulling my hair out

[sircharlo]

Hey guys,

I had a working setup with Nagios and PNP4Nagios on Ubuntu 11.10.
Everything was great.


Then, the other day, I installed NagiosQL, a frontend to configure Nagios.

Since then, PNP4Nagios's web UI doesn't work anymore!


I get this error when trying to access any graph generated by PNP4Nagios:

The requested URL /pnp4nagios/index.php/graph was not found on this server.

The links to the graphs (which worked perfectly before) look like this:

srv-monitor/pnp4nagios/index.php/graph?host=sj-access&srv=ICMP

Why did they stop working all of a sudden?
I have no clue; this is where I'm hoping you guys can help.

Can anyone help?
