MyBB Community Forums

I recently made a new page for my forums, but when I visit the page while I am logged out, I get this error:

Warning [2] Cannot modify header information - headers already sent by (output started at /home/*****/public_html/forums/bans.php:1) - Line: 3102 - File: inc/functions.php PHP 5.2.9 (Linux)

Any advice?

bans.php is outputting content before <?php tags - mostly this is an encoding problem. Make sure that the file is encoded in UTF8 (without BOM), as that will defintely work (that's what MyBB is encoded in, AFAIK).

Notepad++ can change the encoding.
