Comment	> I'm also seeing a lot of 'headers already sent in Unknown on line 0' > in apache error logs. However the manual for flush says: > http://php.net/manual/en/function.flush.php > > flush() may not be able to override the buffering scheme of your web > server and it has no effect on any client-side buffering in the > browser. It also doesn't affect PHP's userspace output buffering > mechanism. This means you will have to call both ob_flush() and > flush() to flush the ob output buffers if you are using those. > > And if I add an ob_flush() call before flush() the error message goes > away. Patch is attached.
