Yes, that '&' is my fault and it will be fixed. It should not be there (I've put & in function call instead of header). But I think that it has nothing common with blank screen. This & is reported as a bug in debug mode (as it was) or sometimes as a warning only in rare php versions, but maybe...
I've sent you PM with link to theme with & bug fixed.
Try it and let me know if it works.
Thanks, finally theme shows at live preview.
however, with a bunch of additional notes in various places:

When I'm trying to activate theme I get white screen with such notices:
