Eh, let's get the latest build, 2.7.0 and I'll help you set it up.
I'm downloading it at the moment to take a look at it, will let you know soon.
EDIT: Completely delete the old version, and unzip 2.7.0 again. Rename the file "config.default.php" to "config.inc.php" and set some things up.
You should just need to edit these three things for starters:
$cfg['PmaAbsoluteUri'], $cfg['blowfish_secret'], and $cfg['Servers'][$i]['auth_type']
