Answer 1

Add ini_set('error_reporting', E_ALL); to the top of the PHP script that is showing a blank page. The blank page is caused by "White Screen of Death" which is when a page errors out but error reporting has been disabled in PHP. re-enabling it by using the above snippet will have PHP output the exact script error to you in your browser.
