Fatal error: Call to a member function getHeader() on a non-object in /home/wank/public_html/sapphire/core/control/Controller.php on line 450
Which refers to

		if($this->response->getHeader('Location')) {

I followed all the instructions. I did have like 400 errors but removed all my addon modules Which the site just kept displaying a big fat error
So i uploaded the installer files again and tried to re-install it all
I don't know what is up with this nightly build but seems its only trouble :( Great scripts though :P
