Full Fix for phpMyAdmin “configuration storage” Error (aaPanel)
1) Import phpMyAdmin internal tables
Log in using root.

mysql -u root -p phpmyadmin < /www/server/phpmyadmin/phpmyadmin_xxxxx/sql/create_tables.sql
(Replace phpmyadmin_xxxxx with your actual folder name.)
2) Create the controluser (pma)
Login to MariaDB:

mysql -u root -p

Run these commands:

DROP USER IF EXISTS 'pma'@'localhost';

CREATE USER 'pma'@'localhost' IDENTIFIED BY 'YourStrongPassword123!';

GRANT ALL PRIVILEGES ON phpmyadmin.* TO 'pma'@'localhost';

FLUSH PRIVILEGES;
EXIT;

3) Edit phpMyAdmin config.inc.php
Open the file:

nano /www/server/phpmyadmin/phpmyadmin_xxxxx/config.inc.php

Uncomment and set these lines (use the same password you created above):

$cfg['Servers'][$i]['controluser'] = 'pma';
$cfg['Servers'][$i]['controlpass'] = 'YourStrongPassword123!';

$cfg['Servers'][$i]['pmadb'] = 'phpmyadmin';
$cfg['Servers'][$i]['bookmarktable'] = 'pmabookmark';
$cfg['Servers'][$i]['relation'] = 'pmarelation';
$cfg['Servers'][$i]['table_info'] = 'pmatable_info';
$cfg['Servers'][$i]['table_coords'] = 'pmatable_coords';
$cfg['Servers'][$i]['pdf_pages'] = 'pmapdf_pages';
$cfg['Servers'][$i]['column_info'] = 'pmacolumn_info';
$cfg['Servers'][$i]['history'] = 'pmahistory';
$cfg['Servers'][$i]['table_uiprefs'] = 'pmatable_uiprefs';
$cfg['Servers'][$i]['tracking'] = 'pmatracking';
$cfg['Servers'][$i]['userconfig'] = 'pmauserconfig';
$cfg['Servers'][$i]['recent'] = 'pmarecent';
$cfg['Servers'][$i]['favorite'] = 'pmafavorite';
$cfg['Servers'][$i]['users'] = 'pmausers';
$cfg['Servers'][$i]['usergroups'] = 'pmausergroups';
$cfg['Servers'][$i]['navigationhiding'] = 'pmanavigationhiding';
$cfg['Servers'][$i]['savedsearches'] = 'pmasavedsearches';
$cfg['Servers'][$i]['central_columns'] = 'pmacentral_columns';
$cfg['Servers'][$i]['designer_settings'] = 'pmadesigner_settings';
$cfg['Servers'][$i]['export_templates'] = 'pma__export_templates';

Save & exit:

CTRL + O
ENTER
CTRL + X
Be careful, you must put your password in this line, both with ssh and in the config.inc.php file.
CREATE USER 'pma'@'localhost' IDENTIFIED BY 'YourStrongPassword123!';
$cfg['Servers'][$i]['controlpass'] = 'YourStrongPassword123!';
