As the errors say, headers already sent.
This means that you have already tried to send text, or something to the
browser, either using an echo, or print statement.
Also check your code, to make sure you have NO whitespace outside the PHP
tags, otherwise this will cause apache to send the whitespace, therefore
removing your ability to set headers.
Headers, as the name suggests must be sent BEFORE you can send any data to
be displayed.
