Description of my issue:
We used SEMINAR from Dirk Vollmer before for the event management of our driving lessons.
When we updated to Joomla 3, we switched to Matukio and install the latest version 3.0.8.
During out setup and testing we found that booking cannot be processed properly.
When registering for an event and providing the credentials in step 1, we get the following message right after clicking "Next":
"Ihre Buchung war nicht erfolgreich! Sie müssen die allgemeinen Geschäftsbedingungen akzeptieren."
However, the AGB are not shown, so there seems to be no way to proceed the event booking.

The booking fields have been reset to default, without any positive impact.

Thank you for your help.

Best regards,
Thomas Bretthauer
