I seem to have fixed this problem.

Amended nginx.conf file:
====================================================================
user www www;
worker_processes 1;
pid /var/run/nginx.pid;
error_log logs/error.log info;

events {
worker_connections 768;
use kqueue;
}

http {
include mime.types;
default_type application/octet-stream;

log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';

access_log logs/access.log main;
sendfile on;
keepalive_timeout 65;
gzip on;

server {
listen 80;
listen 443 ssl;
server_name srvname.com www.srvname.com;

ssl_certificate crt-chain.pem;
ssl_certificate_key key.pem;
ssl_dhparam dhparam4096.pem;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM
EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384
EECDH+aRSA+SHA256 EECDH+aRSA+RC4 EECDH EDH+aRSA RC4 !aNULL !eNULL !LOW
!3DES !MD5 !EXP !PSK !SRP !DSS !RC4";
ssl_prefer_server_ciphers on;

root /usr/local/www/site1/wordpress;
index index.php;

location /phpmyadmin {
alias /usr/local/www/phpMyAdmin/;
index index.php index.html;
}

location ~ ^/phpmyadmin/(.*\.php)$ {
root /usr/local/www/phpMyAdmin/;
fastcgi_pass unix:/var/run/php-fpm.sock;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME /usr/local/www/phpMyAdmin/$1;
fastcgi_param DOCUMENT_ROOT /usr/local/www/phpMyAdmin;
}

location / {
try_files $uri $uri/ /index.php?$args;
}

location ~ \.php$ {
fastcgi_pass unix:/var/run/php-fpm.sock;
fastcgi_param SCRIPT_FILENAME
/usr/local/www/site1/wordpress$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_script_name;
include fastcgi_params;
}

error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/local/www/nginx-dist;
}
}
}
====================================================================

Admittedly, I don't know *why* what I changed fixed the problem, but it
did. I relocated the phpMyAdmin entries to above the "location /" block
from beneath the "location /" block.

From:
http {
server {
root;
location / {
try_files; ... }
location ~ \.php$ {
fastcgi_pass ... }
location /phpmyadmin {
alias; ... }
location ~ ^/phpmyadmin/(.*\.php)$ {
root; ... }
location = /50x.html; {
root; ... }
}
}
}

to:
http {
server {
root;
location /phpmyadmin {
alias; ... }
location ~ ^/phpmyadmin/(.*\.php)$ {
root; ... }
location / {
try_files; ... }
location ~ \.php$ {
fastcgi_pass ... }
location = /50x.html; {
root; ... }
}
}
}

The syntax is identical, just those two location blocks are in a
different place. I would like to know why this works, but am just happy
that it does. I look forward to better understanding this great program.

Thank you, all, for your participation.
