I had the same problem for days until I noticed (how could I look at it and not read the code :-(..) that config.inc.php
is calling config-db.php
** MySql Server version: 5.7.5-m15
** Apache/2.4.10 (Ubuntu)
** phpMyAdmin 4.2.9.1deb0.1
/etc/phpmyadmin/config-db.php:
$dbuser='yourDBUserName';
$dbpass='';
$basepath='';
$dbname='phpMyAdminDBName';
$dbserver='';
$dbport='';
$dbtype='mysql';
Here you need to define your username, password, dbname and others that are showing empty' use default unless you changed their configuration.
That solved the issue for me.
U hope it helps you.
