If I click on your url I get `protocol://www.lourdesphoto.com/zp-core/setup/index.php?autorun=gallery` which somehow looks weird as if there is a constant not defined. That might be a bug although I haven't seen it before.
Try to run setup directly via `http://www.lourdesphoto.com/zp-core/setup/`.
ZPFOCUS is not officially support so it might also be not compatible. But that is surely not the issue here right now.
