Hello. I test the booking system for Joomla 1.7.2 Stable. During installation, I did not get any errors.

When I want to test reservation on the main page, after pressing "Make reservation" I get error:

DateTime::__construct(): Failed to parse time string (2011-11-32 00:00:00) at position 9 (2): Unexpected character

Any solutions?
Tnx
