Error: Could not read host and service status information! Nagios 3

Hi Guys

As you can see this is the error I am getting. Not sure what can be the reason for it but would like if someone can give me some inputs. I had nagios working already but after changing something in windows.cfg and commands.cfg i got this error. When i do service nagios restart it restarts no problem as well as apache is running as well but it gives me this error when i try to access services hopefully someone have clue what to do

Thanks

Did you verify the Nagios process is actually running?

What happens when you do a ps faux | grep nagios ?

this is the output of the command

ps faux | grep nagios
root 13134 0.0 0.1 3596 732 pts/0 S+ 00:31 0:00 \_ grep nagios
nagios 12461 0.0 0.3 14996 1608 ? Ssl Mar30 0:01 /usr/sbin/nagios -d /etc/nagios/nagios.cfg

Is that error coming from the web interface? It's been a while since I've seen that error so don't remember exactly the location.

I assume doing /usr/sbin/nagios -v /etc/nagios/nagios.cfg returns no errors?

I was searching in nagios documentation and found the solution there. I applied the command and it was working then
