Kindly add PHP-Internal option in the panel!
like this --
I am already using the internal function but the problem is it's not showing in the dropdown menu
Internal code
location ~ [^/]\.php(/|$) {
internal;
try_files $uri =404;
fastcgi_pass unix:/tmp/php-cgi-83.sock;
fastcgi_index index.php;
include fastcgi.conf;
include pathinfo.conf;
}
