Oxwall - Internal Server Error

[smtv620]

I've used Softaculous to install Oxwall, and it's giving me an internal server error: http://smt.x10.bz/
I googled around a bit and decided to try installing it manually, which also gave me the same error.

I looked on the site and it says the server needs:

Apache 2 or higher (with mod_rewrite module)
PHP 5.2.6 or higher with:

register_globals off
safe_mode off
suPHP off
suApache off
suhosin off

PHP modules:

PDO
DOM
mbstring
zip
zlib
ftp
json

MySQL 5.0 or higher
GD Library 2 with FreeType support

I was wondering, could it be something to do with the PHP? If so, is there anything I can do to fix it? If not is it possible to have this fixed for me? I know it's a bit of a lot to ask from a free hosting customer.

-edit-
I also HAVE looked at other threads on here, none of them have worked.
