Booking system errors

I have problems with the booking system:
1) http://hvm.simply-webspace.it/old/search/
doesn’t work
2) http://hvm.simply-webspace.it/old/reservation-form/
doesn’t work + coupon system error
http://hvm.simply-webspace.it/old/control-panel/
doesn’t work

Could you help me please?
Thanks in advance, Max
