[TYPO3-seminars] onetimeaccount doesn't log in

[Thorsten Kaltenborn]

Hi there,

I think I configured the extension right since there isn't that much you have to do (systemFolder and group for new users). The user account is created correctly (I tested the account using felogin). But after creating the account the user is redirected to the registration page of seminar manager which displays only that he's not logged in.
Is there anything I can do to test why the user isn't logged in?

Regards 
Thorsten
