Hi, dear developers:

I download your HOTEL theme from
http://www.weebpal.com/drupal-themes/hotel.

And I install your demo site using hotel-demo-7.x-1.x-dev.zip.

Come into the site, in
/admin/rooms/units/unit/14/availability, I click on the calendar, it appears a popup window named Event Management. Here everything is all right.

BUT When I click on Create Standard Booking, it appears a error page as follows:

Fatal error: __clone method called on non-object in C:\xampp\htdocs\hotel\sites\all\modules\rooms\modules\rooms_booking\includes\rooms_booking.availability_agent.inc on line 52

Is it a bug or what?
