A HTTP response is composed of
a. HTTP headers
b. HTTP content
If you try to do
echo 'aaa';
header('ssss');
You will get this error.
Check if the action throws out an error or outputs something, for this
do an exit before
the first header() call in sfWebResponse.
Common situations where I encountered this problem:
1. PHP tags closed that have extra white space at the end of the file
2. UTF-8 BOM signature
