[TYPO3-project-seminars] white page after reg. bug

[DerMediamatiker]

hi there!

typo3: 4.2.6
seminars: 0.7.3
onetimeAcc: 0.4.0

After i make a registration to an event there is just a blank page!
url:

tldh/agendadetails/registration.html?tx_seminars_pi1[seminar]=1&tx_seminars_pi1[action]=register

the email to the user was sent correctly!
any idea?

are there some news about linking to the single page not just with the
title? Perhaps to have linkable date and place? Or how to add a image
in the singleview not as bg image?

thank you very much!

p.s whats going on with the new version?
