[TYPO3-seminars] Using seats

[maris at pt.lu]

Hi.

I'm experiencing a strange behaviour of the seminars extensions.

Everything works fine when I don't use the multiple seats feature. I  
see the confirmation page and the submit registration button and the  
check out page with a summary of my information.

Once I add

plugin.tx_seminars_pi1.showRegistrationFields = seats

then the page which has the submit registration is empty and no  
information is shown. If I click the submit button the registration  
works fine.

I use the One time FE account extension.

Is there something special to add? Where can I find some logs or  
debugging information?

Thx

M
