[fw-mvc] Cannot send headers

Running ZF 1.11.13 and getting the following execption on a
$this->_redirect();

I've checked for trash output and closing ?> tags but I find none.
Anyone have any ideas as to why this might happen. I can render the
pages just find on my local Zend CE server but not on my hosted solution.

Also the pages render just fine if I call them directly. Get the below
error on _redirect();

Thanks
