Warning: Cannot modify header information

Hi I'm getting the following error message on a new dolphin installation when I try edit a member's profile info:

"Warning: Cannot modify header information - headers already sent by (output started at /home/aussie/public_html/modules/boonex/world_map/classes/BxWmapModule.php:1) in /home/aussie/public_html/inc/design.inc.php on line 101"

I've tried re-uploading both BxWmapModule.php and design.inc.php to no avail.

Thanks in advance for any help.

Check line 1 of /modules/boonex/world_map/classes/BxWmapModule.php and make sure there's no whitespace, only <?php.

Thanks again, Nathan.  Do you know what application I can use to convert it to UTF-8 without BOM?  I seem to recall there's a popular notepad replacement that would have this option, but I don't remember its name.

Edit: It turns out I can remove BOM in Dreamweaver.  It's all good now.  Cheers for pointing me in the right direction.

If the file has the closing tag for php, sometimes extra lines after it will trigger the same issue.  Make sure there are no blank; white spaces, at the end of the file.

To fix, open file and make sure it gets saved as UTF8 without a BOM
