Hi guys,
Please i need help.
i have a server with Centos 6.5 + Nginx + PHP-FPM.
I use a website with joomla.
I configured to use Friendly url (SEF) in joomla, and worked, but if i enter something that do not exist like www.example.com/asdasdad, so the server redirect me back to index (www.example.com); but should show me the joomla error page. If i disable the SEF, and test, so i can see the joomla error page. What i need to do ?

I'll send my vhost.conf.

server {
server_name example.com;
return 301 $scheme://www.example.com$request_uri;

location / {

try_files $uri $uri/ /index.php?$args;
autoindex on;
}
