error: ob_end_flush() failed to delete buffer zlib output compression - hard 500 error

[MINORITYmaN]

just for your information referencing to this post http://www.php.net/manual/pl/function.ob-end-clean.php#103817

Take note that if you change zlib output compression setting in
between ob_start and ob_end_clean or ob_end_flush, 
you will get an error:
ob_end_flush() failed to delete buffer zlib output compression

so i made just a small modification (without using htaccess solution) ang changed line: https://github.com/bcosca/fatfree/blob/dev/lib/base.php#L860 to

$ob_get_status = ob_get_status();
if($ob_get_status['name']!='zlib output compression')ob_clean();

cuz having no routing defined in the dev and stable version caused at my hoster an hard 500 error with no output.

Fixed.

if (!count(array_diff(ob_list_handlers(),array('default output handler'))))
    ob_clean();
