Is there any whitespace before your <?php delimiter?
e.g.
===== VERY TOP OF FILE =====
1:
2: <?php
3: /* some code here */
4: ?>
5:
6: <?php header("Location: $page"); ?>
....
The blank lines on lines 1 and 5 would cause header not to work.
The following would also cause a problem:
===== VERY TOP OF FILE =====
1: <HTML>
2: <?php header("Location: $page"); ?>
....
