php - Error when trying to install IPBoard (Invision Power Board)

I'm currently trying to install invision power board as the forum provider for my website, but no matter what I do when i go to /community/ or /admin/install/ i get this error:

I'm with 000webhost and i'm fairly sure they're not the cause, i've also created a MYSQL database for later on in the installation.

I also ensured that all of the files uploaded to the host and double checked this afterwards.

EDIT: The code located within index.php is:

require_once '../../init.php';
\IPS\Dispatcher\Setup::i()->setLocation('install')->run();
