Reupload the file and then user the admin interface to change the title.

admin -> Edit Server Settings -> Message Board Name

Unless you mean the page title

Sounds like something is wrong with index.php; it shouldn't be outputting anything on line 1.

(for future reference)

Yes, it seems that for some reason with some of the web-based editors supplied with web-administration software (e.g. Control Panel) some new lines seem to get inserted at the end of a file when you've been editing it.  This is sufficient to generate HTML output (since they follow the '?>', , causing the "headers already sent" error.

That's what my problem was with the same set of error messages after having edited the Settings.php file directly upon migrating to a new host.
