Why does phpMyAdmin show an almost empty page instead of the login page?

Why does phpMyAdmin show an almost empty page instead of the login page?

I installed phpMyAdmin with Nginx and MariaDB on my FreeBSD server at home. When I visit the login page, I see this instead of a login page:

Here are the versions of the different components:

  • FreeBSD 15.0
  • Nginx 1.30.4
  • MariaDB 12.3.2
  • PHP 8.6.0alpha1

usr/local/etc/mysql/my.cnf contains the following (plus commented out lines):

[client-server]
port    = 3306
socket  = /var/run/mysql/mysql.sock

I added the following in /usr/local/www/phpMyAdmin/config.inc.php:

$cfg['Servers'][$i]['socket'] = '/var/run/mysql/mysql.sock';

The config block I added for Nginx is the following:

server {
        listen 80;
        #server_name app.example.com;
        root /usr/local/www/phpMyAdmin;

        index index.php index.html index.htm;

        location / {
                try_files $uri $uri/ =404;
        }

        location ~ \.php$ {
                include fastcgi_params;
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        }

        error_page 404 /404.html;
        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
                root /usr/local/www/phpMyAdmin;
        }
}

The logs don't contain anything useful to figure out what's wrong. I tried with different versions of php and phpMyAdmin and different browsers, but I get the same result. I searched online and didn't find any post describing the same problem.

What am I missing?

Update 1: When I comment out the line I added in /usr/local/www/phpMyAdmin/config.inc.php and restart the services, the login page is reachable, but credentials that are either valid or invalid yield the same error:

/var/log/php-fpm.log is a repetition of the following:

Update 2: I tried Bilal's suggestion to downgrade to an earlier version of PHP:

$ php -v
PHP 8.2.32 (cli) (built: Jul  9 2026 03:03:59) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.2.32, Copyright (c) Zend Technologies
$ php -m
[PHP Modules]
bz2
Core
ctype
date
filter
gd
hash
iconv
json
libxml
mbstring
mysqli
mysqlnd
openssl
pcre
random
Reflection
session
SPL
standard
xml
xmlwriter
zip
zlib

[Zend Modules]

However this doesn't solve the problem.

Update 3: As requested by Ramhound:

/usr/local/www/phpMyAdmin/config.inc.php:

<?php
/* Skeleton configuration file -- this file is empty on a fresh
 * installaton of phpmyadmin.
 *
 * Copy any settings you want to override from
 * libraries/config.default.php or visit /phpmyadmin/setup/ to generate a
 * basic configuration file
 *
 */

$cfg['Servers'][$i]['socket'] = '/var/run/mysql/mysql.sock';

?>

Update 4: To make sure the config file I am editing is read by Nginx, I added a garbage line in it. Restarting Nginx yields the following:

Performing sanity check on nginx configuration:
nginx: [emerg] unknown directive "asdfasdfasdfasdf" in /usr/local/etc/nginx/sites-enabled/phpmyadmin.conf:11
nginx: configuration file /usr/local/etc/nginx/nginx.conf test failed

Output of different commands requested in the comments:

/usr/local/sbin/php-fpm -v:

Note that using the absolute path or not doesn't change anything because which php-fpm returns /usr/local/sbin/php-fpm.

Top Answer/Comment:

Look at your own screenshot: PHP version, PHP extension, and database client version are all blank. That's the tell. Those get filled in by PHP at runtime, so the problem is PHP, not nginx or your socket.

You're on PHP 8.6.0alpha1, and phpMyAdmin 5.2.3 doesn't support it. It's an alpha (a dev snapshot), while 5.2.3 was written for stable PHP up to ~8.2. On an alpha you get exactly this: the static HTML renders, but the parts that call into mysqli and PHP internals fail quietly, so no login form and blank version fields.

What you should do?

Drop back to a stable, supported PHP (8.2, or 8.3 at most) and restart php-fpm.

Make sure the mysqli extension is installed and loaded (php82-mysqli, matching your PHP version) and shows up in php -m. That blank "PHP extension" line is where mysqli should appear, so it may not be loaded at all.

Do the PHP downgrade first; the login page should come right back.
