Just installed CI4 RC1 but getting blank pages

apache. domain.com outputs blank page, domain.com/controller/method outputs blank page.

figured its something to do with output_compression is php, if set to On, i get headers already sent errors and blank pages. if set to Off, all works fine. 

OR

if i remove 

Code:

while (\ob_get_level() > 0)
    {
        \ob_end_flush();
    }

    \ob_start(function ($buffer) {
        return $buffer;
    });

 from /app/Config/Events.php and keep output_compression on, it works.


I have submitted a bug here: https://github.com/codeigniter4/CodeIgni...ssues/2182
