Using PhpMyAdmin with PHP and MySQL stack in Ubuntu I encounter the problem: 
      
  TO solve this I added: 
  $ Cfg [‘Servers’] [$ i] [‘table_uiprefs’] = ‘pma_table_uiprefs'; 
  Changed to: 
  $ cfg [‘Servers’] [$ i] [‘pma__table_uiprefs’] = ‘pma__table_uiprefs'; 
  in  config.inc.php file after that I've got the problem like: 
     Error in Processing Request
      Error code: 200
      Error text: OK
 
  How can I solve this?
       looks like your config has been modified put this in /var/www/phpmyadmin/config.inc.php and also change password below if you set something else blank
  $cfg['blowfish_secret'] = 'a8b7c6d'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */  /*  * Servers configuration  */ $i = 0;  /*  * First server  */ $i++; /* Authentication type */ $cfg['Servers'][$i]['auth_type'] = 'config'; /* Server parameters */ $cfg['Servers'][$i]['host'] = 'localhost'; $cfg['Servers'][$i]['connect_type'] = 'tcp'; $cfg['Servers'][$i]['compress'] = false; /* Select mysql if your server does not have mysqli */ $cfg['Servers'][$i]['extension'] = 'mysqli'; $cfg['Servers'][$i]['AllowNoPassword'] = true; $cfg['Servers'][1]['user'] = 'root'; //edit this line $cfg['Servers'][1]['password'] = 'XXXX'; // your password 
  and comment this line for now
  //$ cfg [‘Servers’] [$ i] [‘pma__table_uiprefs’] = ‘pma__table_uiprefs';
