phpMyAdmin – Invalid hostname for server 2

If you have installed phpMyAdmin, you may get the errors

Invalid hostname for server 2. Please review your configuration.
Invalid hostname for server 3. Please review your configuration.

when you log in. If so, the solution is to comment out this block of code in config.inc.php (it appears twice) - just wrap it in '/*' and '*/' as I have below

PLAIN TEXT

PHP:

1. /* This has been commented out because of error message
2. $i++;
3. $cfg['Servers'][$i]['host']            = '';
4. $cfg['Servers'][$i]['port']            = '';
5. $cfg['Servers'][$i]['socket']          = '';
6. $cfg['Servers'][$i]['connect_type']    = 'tcp';
7. $cfg['Servers'][$i]['extension']       = 'mysql';
8. $cfg['Servers'][$i]['compress']        = FALSE;
9. $cfg['Servers'][$i]['controluser']     = '';
10. $cfg['Servers'][$i]['controlpass']     = '';
11. $cfg['Servers'][$i]['auth_type']       = 'config';
12. $cfg['Servers'][$i]['user']            = 'root';
13. $cfg['Servers'][$i]['password']        = '';
14. $cfg['Servers'][$i]['only_db']         = '';
15. $cfg['Servers'][$i]['verbose']         = '';
16. $cfg['Servers'][$i]['pmadb']           = ''; // 'phpmyadmin' - see scripts/create_tables.sql

24. $cfg['Servers'][$i]['verbose_check']   = TRUE;
25. $cfg['Servers'][$i]['AllowDeny']['order']
26.                                        = '';
27. $cfg['Servers'][$i]['AllowDeny']['rules']
28.                                        = array();
29. */

Thanks! I was just upgrading our phpMyAdmin, and came across the same problem - your post was very helpful.
