An extra space or characters has been inserted into the calendar.php or config.in.php file. It'll be at the beginning or the end of the file.

Brian, not so ggod at php, how do know what to look for exactly, not sure if I would reconize a extra space, viewing with Ultra Edit

[Brian]

There should be absolutely nothing before <?php and after ?> in the calendar.php, license.php and config.inc.php files.
