Admin account after install

After Elgg has installed, and the area where one would usually create their 'admin' account, all I get is a blank page, and also if I try and register.

Example:

http://lrconline.info/community/elgg/account/register.php

I did manage a successful install, however, I managed to 'break' it with a mod, or the mod managed to beak it, either way I deleted the elgg directory, database and any relevant stuff, downloaded elgg 1.5 and that happened. Also tried 1.6 but still the same. My first guess would be some sort of missing php extension, but, last I checked, it meets the requirements.

Also should add, I've tried uploading elgg in several ways, FTP and cPanel mainly. And also tried downloading Elgg a few times.
