phpMyAdmin reports on startup that the configuration doesn't have storage completely configured. Following the instructions in the Documentation I added the following lines to the config.inc.php file:-
$cfg['Servers'][$i]['recent'] = 'pma_recent';
$cfg['Servers'][$i]['table_uiprefs'] = 'pma_table_ui_prefs';
The tables do already exist in the DB.
When I restart phpMyAdmin it says it can't read the configuration file!
