Joomla 2.5, PHP 5.3.3 (fpm-fcgi), nginx 1.4.2
Nginx is up & running, I can access my site's home page & other site URLs that end index.php just fine.
However when I browse to a Joomla category whose URL is in the form: http://www.mysite.com/index.php/features/modules I always get a 404.
Articles seem to work fine too (in the form http://www.mysite.com/index.php?Itemid=404) it just appears to be categories where "index.php" isn't involved.
Can anyone suggest what I need to add to my nginx conf to fix this please?
Thanks,
Steve
