I cannot use ob_flush() because my lib is loaded on auto_prepend_file. ------------------------------------------------------------------------ [2014-08-31 01:35:00] stas@php.net BTW, if you add a flush at the end of the script, this also fixes the issue. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
