I saw the same problem on Dapper. dpkg --status phpmyadmin reports: Version: 4:2.8.0.3-1
I fixed it by adding this: require_once('/etc/phpmyadmin/blowfish_secret.inc.php'); after the first line ("<?php") of: /usr/share/phpmyadmin/libraries/auth/cookie.auth.lib.php I logged in successfully. Then, I removed that line and I was still able to login, even from other computers after a full (force-reload, not graceful) restart of Apache. So, I'm not sure what happened. It'll be a little while before I try on another server. -- Silly problem with a parameter https://launchpad.net/bugs/42201 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
