Check your code again, anda again! Because somewhere you already starts to output something - hence the error messsage. Not /if/, but /when/ you are 115% sure you have no segment of code that been outputing some HTML, then your error message may be caused by (the failure of) shell execution of a command. Do you you php script call any external programs? -----Original Message----- From: susilo soewarno To: Svensson, B.A.T.
