If you use this version, be sure to check your server software before installing new version. The version 4.5 is compatible with PHP 5.5 to 7.0 and MySQL 5.5. MyAQL 5.5 means or later, I think. My SQL sever is MariaDB10.0 and has no problem.
Upgrade from phpMyAdmin 4.4.x to phpMyAdmin 4.5.x now.
1) Download phpMyAdmin-22.214.171.124-english.zip.
2) On the server, rename the folder phpMyAdmin to phpMyAdmin_old. Extract the Zip archive. Rename the folder phpMyAdmin-126.96.36.199-english to phpMyAdmin. Copy the old config.inc.php to the phpMyAdmin folder.
3) Access http://YourDomain/phpmyadmin/ as root. You will have two warnings because new version have two new directives – See the right image. Make two tables on the database phpmyadmin by importing the SQL file which I made from original create_tables.sql that you can find in the sql folder of the phpMyAdmin folder.
4) Edit the config.inc.php.
Add the following lines below the line $cfg[‘Servers’][$i][‘central_columns’] = ‘pma__central_columns’;.
$cfg['Servers'][$i]['designer_settings'] = 'pma__designer_settings';
$cfg['Servers'][$i]['export_templates'] = 'pma__export_templates';
5) Access http://YourDomain/phpmyadmin/ as root again. The warnings have gone.
