Most likely that is exactly what's happening. To be even more clear -
the solution is to use the header function before any HTML (before *any*
output). I learned this when I had an include file that was all Php
causing this problem. The end of the included file had a carriage return
after the closing tag ?>. That was a nasty one to locate. Now I always
make sure there is no white space after the closing tag in files I might
include somewhere else.
