Forbidden to all virtual host

Hello all,

Yesterday I updated virtualmin and tried to install nagios on Centos 6.7 but now all websites are showing forbidden error
You don’t have permission to access / on this server.

Apache is working fine.
IPTables have not blocked port 80

I checked apache logs they are as follows
[Tue Aug 18 17:19:00 2015] [error] [client xxx.xxx.xxx.xxx] (13)Permission denied: access to / denied

What can be done?

Howdy,

Which Apache log are you seeing that Permission Denied error in – is that in the system log located in /var/log/httpd/? Or is that in the user’s homedir in $HOME/logs?

Also, what is the output of this command:

rpm -qa | grep httpd
