[wp-hackers] wp_redirect() fails on Linux

[AJ Chen]

My web2x plugin uses wp_redirect() to start post editor:
wp_redirect("http://web2express.org/openlab/wp-admin/post.php?w2x=prj");

It works in my windows xp development environment, but it fails on linux
server with error message:
*Warning*: Cannot modify header information - headers already sent by
(output started at /home/ajchen/public_html/openlab/wp-admin/admin-
header.php:16) in */home/ajchen/public_html/openlab/wp-includes/pluggable-
functions.php* on line *272

*Line 272 is
header("Location: $location");
