I have my forum installed on my localhost and it works, but when i upload it and try to login appears the following error:

Warning: Cannot modify header information – headers already sent by (output started at Inetpubwebsllibreviuorgtestforoconfig.php:1) in Inetpubwebsllibreviuorgtestforobb-includespluggable.php on line 37

What i have to do?

That is usually because of whitespace after the ?> at the end of a php file (could be before the beginning <?php too.)

Check any files you might have edited (config.php?) and make sure there are no blank lines at the beginning or the end. That should take care of it.
