'Prefix of tables' value/entry is not used for creating tables in Wordpress database. Random value is taken in wp-cofig.php as well as in tables of database.


Bug #PPPM-2056. It is fixed in Plesk Onyx.


Upgrade to the latest Plesk version.

If upgrade is not possible:

Plesk generates random prefix only if 'Wordpress Toolkit' is enabled (it depends on license key or setings in panel.ini):


#cat /usr/local/psa/admin/conf/panel.ini

Windows: %plesk_dir%\admin\conf\panel.ini

The possible workaround is to disable Wordpress Toolkit. In this case table name will be 'myprefix' + 'wp_' + 'tablename'. For example:

mysql> show tables

This is because configuration script in the Wordpress package has the following line:

$db_modify_hash['@@DB_MAIN_PREFIX@@'].='wp_'; // Means that db prefix will be "myprefixwp_".  

There should not be any technical problems to remove adding 'wp_' from Wordpress configuration script.

Wordpress install not using table prefixes

Plesk still enters a random prefix for database tables
