Issues after changing permalinks

Hi,

After I change the permalink style from Plain to any of the other options, I encounters errors – mainly with forms.
Login/Logout/Contact forms etc. do not appear to do anything.

In the Nginx error log, the following errors appear:

2019/07/17 15:09:24 [error] 26688#0: *1 "/data001/***/***/***/***/***.com/index.php/my-account/customer-logout/index.php" is not found (20: Not a directory), <truncated>

Nginx and php-fpm are running as nginx and the directory is owned by nginx (755/644) permissions.

The appending of index.php to the URL seems odd.
But I’m not sure why this is happening.
I’ve always used Apache, but opted for Nginx to get better performance.
So I think the issue may be due to my limited knowledge here.

Nginx Config:

    location / {
        #try_files $uri $uri/ /index.php;
        try_files $uri $uri/ /index.php?$args;
        #try_files $uri $uri/;
        include /***/***/***/***/***/***.com/nginx.conf;
    }

location ~ .php$ {
        #try_files $uri =404;
        try_files $uri $uri/ /index.php?$args;
        #try_files $uri $uri/;
        include /***/***/***/***/***/***.com/nginx.conf;
        #fastcgi_pass 127.0.0.1:9000;
        fastcgi_pass unix:/var/run/php7.0-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
