What´s the "total capacity" setiing about?
For example object is a car, so if I set there number 2, it means i have 2 cars and customers can make 2 reservations in the same time period?

Sorry, when I try it with next month it´s OK, probably is this object set to be unavailable untill 2.5.2011, isn´t it?

Today i tryed Your demo for example on demo.tramin.artio.cz/joomla15/en/car-ren...avia-2-tdi-1/subject and I cant make reservation there too. So I think problem can be in browser settings...

Same problem, everthing works fine but you can´t make reservation. I tried modify date format in configuration (it solves this problem in previous versions-in version 1.2.3 not )
If you want, I can send you complete backup of the site. My system parameters:

If you need to translate the text "Who reserved", insert the line "WHO RESERVED=Who reserved" to en-GB.com_booking.ini and in my case "WHO RESERVED=Kdo rezervoval" to cs-CZ.com_booking.ini

When you need using an hour type of booking, use %d-%m-%Y %H:%M for long format and %d-%m-%Y for short

I´m not able to make reservation of object if I´m logged in as joomla user which is not in booking component in customers list. The mod_booking_customer_info reports me I´m not logged as customer but there is no way to become a customer with your existing Joomla acout.
If I make a reservation, I can fill all fields like name surname phone and so on, but my registration isn´t saved without any error message .

When I´m not loged in Joomla , I can create a new acout from mudule mod_booking_customer_info whitch is attatached to component customers acout and everising works fine.
If I have allowed booking to unregistred, unregistred can make reservation, but joomla users not in customers list again are not able to do it.

Em I dum, or it´s error?
