Issue Nginx not handling index.php, passed to Apache instead

[OlgaKM]

I have set the settings on my server to run PHP 7.0 via nginx + php-fpm. When I access a script by name, e.g. "http://www.somedomain.com/index.php", this works correctly. However, if I access "http://www.somedomain.com/", the script is executed, but handled not by nginx + php-fpm, but by Apache. I can tell because the script is a simple phpinfo() script: when nginx handles it, the PHP version is listed as 7.0, while when Apache does it, it's listed as 5.4, which is the default PHP version on my system (OS vendor does not support anything higher).

I do not have any custom nginx or Apache directives set up on this domain. Any tips on resolving this issue?

It looks as if you have still enabled "Proxy mode" in the "nginx" section of the "Apache & Nginx Settings" of the domain, because in your configuration file the proxy sections are still present. If proxy mode is enabled, all file requests that are not in the "static" file extension list will be proxied to httpd. For that reason the .php extension can be identified as PHP, but an "empty" extension (for the index page) will not be identified to be handled by the PHP module for Nginx. Please try to disable proxy mode, restart Nginx afterwards to have it read the new configuration (or wait until the restart interval expires) and test again.

Edit: Oops, sorry, I made a mistake. You have posted this in the 12.x section. The setting I have considered is not available in Plesk 12.x, it is only available in 17.x or younger. I'll need to think about this again then. It's probably the correct reason given, but you need a different solution, because in 12.x you cannot do Nginx-only hosting.

I *do* have a checkbox for "Serve static files directly by nginx" in the Apache & nginx settings page. Is this what you're referring to?

Also, might a block like the following work?

location @proxy {
               proxy_pass http://XXX.XXX.XXX.XXX:7080;
               proxy_set_header Host             $host;
               proxy_set_header X-Real-IP        $remote_addr;
               proxy_set_header X-Forwarded-For  $proxy_add_x_forwarded_for;
               proxy_set_header X-Accel-Internal /internal-nginx-static-location;
               access_log off;
}

location ~ /$ {
               try_files $uri/index.php @proxy;
}
