I'v updated my test-site directly from 2.1 to the new 2.2.2 rc2 version.

But now i can't login anymore.
And so, i can't update Database...
Send password via email doesn't work, becouse email is only a nickname...

If i've a look at the dbtables using phpMyAdmin (Members)
i can see 'my' row in Table with columns 'Email' and 'Password'.
The things are exactly the same as i'm trying to enter in the login box.
But it doesn't work.

Maybe it's a Problem, becouse Email is not a real Email?
(only a nickname)

So is there a way to 'reset a admin-password'?
Do i have to update to 2.2.1
first before upgrade to 2.2.2rc2?

Would be happy about any answer.
am not that over-experienced silverstirp user till now..

From http://doc.silverstripe.com/doku.php?id=upgrading:

Login Form

Check that you have a Layout/Page.ss file for your site, or alternately have a Security_login.ss template.

Your template file needs a $Form variable for it to work. This is where the login form gets included.

Without either of these, the Security/login form will be blank.
