Magento Debug HEADERS ALREADY SENT error

Question

I am receiving the following error in my system.log file:

 2011-01-12T14:16:52+00:00 DEBUG (7): HEADERS ALREADY SENT: 
 [0] C:\\xampp\\htdocs\\www.mysite.com         


        

Answer 1

I have the same problem while installing Magento.

In my case enabling output_buffering in PHP solved the issue.

In xampp with PHP 5.6 output_buffering is enabled by default.

In xampp with PHP 5.3 output_buffering is disabled by default.
