Apache上的空白PHP页面

Question

I am trying to migrate an OpenX adserver to a new server. Apache, MySQL and PHP are all installed, but when accessing the site from any browser, a blank white page is displayed.

I have tried putting a one-line .html file and a PHP file with phpinfo(); in it - both work just fine, the PHP file displays all relevant information, but the default administration login page doesn't load.

The file structure and the database were copied over from the previous server (where everything worked perfectly) and I have modified the Apache Virtual Server settings to have it show to the current directory where the files are located.

The OS on the new server is Ubuntu 14.04 LTS.

Any ideas what could be going wrong?

By default, PHP displays a blank page when an error occurs. Check your error.log or add the following to your PHP:

error_reporting(E_ALL);
ini_set('display_errors', 1);
