“Connection for controluser as defined in your configuration failed” with phpMyAdmin in XAMPP

Question

I have just installed XAMPP on my Windows XP machine, and I get an error saying:

Connection for controluser as defined in your configuration failed.

Answer 1

on ubuntu /etc/phpmyadmin/config-db.php

make sure the password matches your config.inc.php for the control user

also for the blowfish too short error

edit /var/lib/phpmyadmin/blowfish_secret.inc.php and make the key longer
