I don't have any problem on localhost. but when i tested my codes on server, end of every page i see this notice.
my code:
<?php
ob_start();
include 'view.php';
$data = ob_get_contents();
ob_end_clean();
include 'master.php';
ob_end_flush(); // Problem is this line
It solved when switched off zlib.output_compression in php.ini
zlib.output_compression = Off
