Mysql – phpMyAdmin: The additional features for working with linked tables have been deactivated

I'm getting this error in the main page of phpMyAdmin verson: 3.2.1deb1
The additional features for working with linked tables have been deactivated. To find out why click here.
When I click the link I get this report.

$cfg['Servers'][$i]['pmadb'] ...    OK
$cfg['Servers'][$i]['relation'] ...     not OK [ Documentation ]
General relation features: Disabled

$cfg['Servers'][$i]['table_info'] ...   not OK [ Documentation ]

$cfg['Servers'][$i]['history'] ...  not OK [ Documentation ]

$cfg['Servers'][$i]['designer_coords'] ...  not OK [ Documentation ]

I already used the script to create the tables.
I assigned the permissions to the pma user.
And everything is set in /etc/phpmyadmin/conf.inc.php

But it's still not working…
The tables are empty. I assume that they should have something.
I'm interested in the relations an history features.
Obviously I have read the documentation.
Maybe something else is unsetting those values?
Any toughs?
