Use some random URL parameter and detect it in your script. When detected enabled display errors: <?php if( isset( $_GET['knjdcrksjhfcsjkhfndkf'] ) ) { ini_set( 'display_errors', 1 ); } ?> Then see if you get any errors. Although, if you're seg faulting, you still won't see an error since the program just dies. Cheers, Rob. -- ...........................................................
