Fix “Configuration of pmadb… not OK” in phpMyAdmin

You may get this message in pmpMyAdmin:

To fix this you have to import/create the phpmyadmin database with it's tables. An SQL script called create_tables.sql should be in the scripts, examples or sql folder of your phpMyAdmin installation.

mysql -u root -p < create_tables.sql

Then create a user called pma and give it permissions to the phpmyadmin database:

CREATE USER 'pma'@'localhost' IDENTIFIED BY 'pmapass';
GRANT ALL PRIVILEGES ON `phpmyadmin`.* TO 'pma'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;

Now edit config.inc.php and configure/uncomment those lines:

/*
 * phpMyAdmin configuration storage settings.
 */

/* User used to manipulate with storage */
$cfg['Servers'][$i]['controlhost'] = 'localhost';
// $cfg['Servers'][$i]['controlport'] = '';
$cfg['Servers'][$i]['controluser'] = 'pma';
$cfg['Servers'][$i]['controlpass'] = 'pmapass';

/* Storage database and tables */
$cfg['Servers'][$i]['pmadb'] = 'phpmyadmin';
$cfg['Servers'][$i]['bookmarktable'] = 'pma__bookmark';
$cfg['Servers'][$i]['relation'] = 'pma__relation';
$cfg['Servers'][$i]['table_info'] = 'pma__table_info';
$cfg['Servers'][$i]['table_coords'] = 'pma__table_coords';
$cfg['Servers'][$i]['pdf_pages'] = 'pma__pdf_pages';
$cfg['Servers'][$i]['column_info'] = 'pma__column_info';
$cfg['Servers'][$i]['history'] = 'pma__history';
$cfg['Servers'][$i]['table_uiprefs'] = 'pma__table_uiprefs';
$cfg['Servers'][$i]['tracking'] = 'pma__tracking';
$cfg['Servers'][$i]['designer_coords'] = 'pma__designer_coords';
$cfg['Servers'][$i]['userconfig'] = 'pma__userconfig';
$cfg['Servers'][$i]['recent'] = 'pma__recent';
$cfg['Servers'][$i]['favorite'] = 'pma__favorite';
$cfg['Servers'][$i]['users'] = 'pma__users';
$cfg['Servers'][$i]['usergroups'] = 'pma__usergroups';
$cfg['Servers'][$i]['navigationhiding'] = 'pma__navigationhiding';
$cfg['Servers'][$i]['savedsearches'] = 'pma__savedsearches';
$cfg['Servers'][$i]['central_columns'] = 'pma__central_columns';
$cfg['Servers'][$i]['designer_settings'] = 'pma__designer_settings';
$cfg['Servers'][$i]['export_templates'] = 'pma__export_templates';

Finally logout and login again to phpMyadmin.
