Web server showing blank page

[17100113]

Hi, I just cloned your web folder into my git and deployed it onto a web server but whenever I try to access the session.php it just shows a blank page with nothing. No HTML elements, nothing. Its completely empty. Can you kindly have a look at it and tell me what Im doing wrong? Also I had to change the name of the file session.php to index.php so that it opens that as default page. If I keep it to session.php it doesnt even deploy and gives an error. Im deploying it to heroku. Here's the link to the git and the heroku web server

Try to change the PHP Version.
When PHP V7 is active the server shows blank pages.
Try to set the PHP version to V5.

Kind regards
Kamikaze

BTW, I'm using PHP v7 for Torque - and it's working perfect.
