Re: ob_gzhandler problems under 4.3.0???

PHP is starting output buffering automatically for you and then you are starting it in your script as well, that is why you are receiving the message ob_gzhandler can not be used twice. Use ob_get_level to check if output buffering is not already started. <?php // start output buffering if it is not already running if (0 == ob_get_level()) { ob_start('ob_gzhandler'); } ?> You may want additional logic that checks to see if the output buffer hander is ob_gzhandler.
