Solution - Installed LAMP, PHP works, but website shows a blank page!

Problem:
Recently I've been setting up some servers for web hosting and while install the LAMP stack, ran into a funny issue where the server would return a blank page when I tried to access the PHP website.

Solution:
After checking logs, and playing with settings, I realized I had made a bad assumption. The server hosted PHP version 5.3.3, but the libraries in use required PHP 5.3.7. After installing a newer version of PHP, everything went worked great.
