As stated on the manual page http://php.net/ob_start

Output buffers are stackable, that is, you may call ob_start() while
another ob_start() is active. Just make sure that you call ob_end_flush()
the appropriate number of times. If multiple output callback functions are
active, output is being filtered sequentially through each of them in
nesting order.

In essence, you have to use one ob_end_flush() for each ob_start() you
have, or an equal number of ob_end_flush() as you have ob_start(). If you
have ob_start() at the start of your main file or included file, you
should also have an ob_end_flush() at the end of that same file.
