The error is in mailform.php on line 79.

My guess is that that's the last line of mailform.php, and it contains a 
line end or a blank after the closing ?> bracket. (PHP emits anything 
outside of <?php...?> as HTML source, and that makes it impossible to 
sent HTTP headers afterwards; part of PmWiki's normal operation is to 
set these headers though.)
