<?php ?>
in your header.php include file.
Whitespace can cause a premature output in PHP which can cause the above error.

14,925 PointsI encountered the same issue and the solution over at the post below fixed it for me. I'm running MAMP locally and Output Buffering is not enabled by default so the function obstart()
needs to be run for the warning to disappear.
